Question 2

2007-05-13T13:48:00.000-05:00

Susan is making a jump to ride her bike over. She uses a 1m plank of wood to make the jump, and raises the end 50 cm off the ground with a second piece of wood. How far along the ground from the end of the plank that touches the ground is the second piece of wood?

SINCE ADDING SIDE A AND SIDE B GIVES YOU SIDE C, TAKE AWAY SIDE A FROM SIDE C TO GET SIDE B

OR

C² - A² = B²

WITH THAT YOU CAN THIS:

C² - A² = B²...FORMULA
10² - 6² = B²...REPLACE A & C
(10X10) - (6X6) = B²...SQUARE A & C
100 - 36 = B²
64 = B²...SUBTRACT

YOU ARE NOT DONE YET. YOU FIVE B², YOU ARE LOOKING FOR B. YOU STILL HAVE TO FIND THE SQUARE ROOT OF YOUR ANSWER TO FIND B.

THE SQUARE ROOT OF 64 IS 8 (8X8=64).

B = 8

Finding C

One of the most famous mathematicians who has ever lived, Pythagoras, a Greek scholar who lived way back in the 6th century B.C. (back when Bob Dole was learning geometry), came up with one of the most famous theorems ever, the Pythagorean Theorem. It says - in a right triangle, the square of the measure of the hypotenuse equals the sum of the squares of the measures of the two legs. This theorem is normally represented by the following equation: a2 + b2 = c2, where c represents the hypotenuse.

With this theorem, if you are given the measures of two sides of a triangle, you can easily find the measure of the other side.

Example

1. Problem: Find the value of c.

Accompanying Figure

Solution: a2 + b2 = c2 Write the Pythagorean
Theorem and then plug in any
given information.

52 + 122 = c2 The information that was
given in the figure was
plugged in.

169 = c2 Solve for c By finding the square root of the number
c = 13

2. Problem: A ladder 12 meters long leans
against a building. It rests on
the wall at a point 10 meters
above the ground. Find the angle
the ladder makes with the ground.

Solution: Make sure you know what is being
asked. Then use the given
information to draw and label a
figure.

a2+b2=c
12,2+10,2=c
c2=144+100
c=244
square root of 244 is 15.62
c=15.62

Overall the fraction unit was easy. I knew how to do the adding and subtracting. Multiplying fractions wasn't that hard either. Dividing was the hardest but I understand it know. One of my problems that I had in this unit was I would forget to convert mixed fractions into improper fractions when I needed to.

Did you like the unproject?
I didn't really like the unproject but it wasn't bad either. It was alright.

Did the unproject make you work harder than you usually would?
I think the unproject did make me work harder than I usually would.

What did you like best about the unproject?
The best part about the unproject was when it was done.

What would you change about the next unproject?
I guess I would put more effort in the next unproject.

Did the unproject make you learn more because you were doing a different type of project?
I don't think it made me learn more but it was sort of like a review.

APRIL T'S BOB
On this Fraction unit, i had a hard time with dividing fractions and knowing when to divide or multiply in a word problem. I'm still struggling with that. I think the easiest for this unit was adding, subtracting and all those other ones we did. My purple booklet was fun to do. HEHE (:

Did you like the unproject?
Yes, I liked doing the unproject because in a way it was fun, and educational at the same time.

Did the unproject make you work harder than you usually would?
Yes, it did make me work harder than usual because i wanted everything to be perfect so i required a little more work.

What did you like best about the unproject?
I liked making pictures and making the quiz. It was fun because we could put any number we like on the quiz.

What would you change about the next unproject?
I think i would start it when he assigns it to us so it wont be late.

Did the unproject make you learn more because you were doing a different type of project?
Yes, it made me learn more because as i explain about what to do when adding and subtracting, and also multiplying and dividing it made me learn as i was working.

This fraction unit was sort of easy, multiplying and dividing fraction was probably the part in the unit that was sort of hard. I finished my purple book on time, but in some of the pages the answers don't really seem like their right. I did pretty good on all of my tests and quizzes. Adding, subtracting, finding lcd was pretty easy.

Did you like the unproject.
Yeah I liked doing the unproject because in a way it was fun.

Did the unproject make you work harder than you usually would?
Yes the unproject made me work harder than I usually would work because it took a lot of effort just to make it how I wanted it to be and it's worth ten percent of your mark.

What did you like best about the unproject?
The most thing I liked about doing the unproject was making the pictures.

What would you change about the next unproject?
I would add more pictures and explain the things a bit better.

Did the unproject make you learn more because you were doing a different type of project.
Yes the unproject made me learn more about fractions.

The fraction unit was easy. I found adding easy. I found dividing hard at first. I didn't do my purple sheet on time which was my weakest in this unit. I liked the unproject. The unproject made me work harder then usually. The best thing about the unproject was doing the questions. If i had a chance to change my unproject i would put more creative stuff. The unproject made me learn because i did different type of project.

In unit wasn't easy for me at first. But once I got help I got the hang of it. The adding and the subtracting was easy for me to do, but I did ask for help on the dividing and multiplying parts. I did my work on the purple booklet but in some parts I didn't put in how I got the answer. I also put in some of the notes in my big paper.

1.) Did you like the unproject.
- I didn't really enjoy it as much as I thought of, but I did learn stuff on my topic.

2.)Did the unproject make you work harder than you usually would?
- No, this unproject assignment didn't really make me work harder than I usually did for my math and other subject assignments.

3.)What did you like best about the unproject?
- The thing I liked best about this unproject assignment was making pictures. "I like doing things on paint!" :D

4.)What would you change about the next unproject?
- Well I think what Alyssa and I have done is pretty well done. I would also want to put on a quiz on our wikispace as well too. :)

5.)Did the unproject make you learn more because you were doing a different type of project.
- Yes, while doing this unproject assignment I learned more about fractions.

This unit (fractions) was pretty hard for me in the beginning of the unit then i started to do well. I learned alot of things that i didn't learn when i was in grade 1 to 6 like for adding i sometimes forget how to do it then i remember how to do it. I have problems for dividing because i always forget the process of doing it so i have to look it over before tests and the exam. Also multiplication i still have to work hard on that. Adding and Subtracting is okay for me.

BOB
Did you like the unproject.
I enjoyed doing the unproject i learned alot about fractions and how to explain them.
Did the unproject make you work harder than you usually would?
Yes it did i stayed after school and at lunch times to finish it up and Joshua and me completed it and finished before the deadline.
What did you like best about the unproject?
I liked the part where we did the definitions about the fractions and drawing the pictures for the fractions.
What would you change about the next unproject?
I would probably do another unproject like a movie or an animation because that looked very interesting to do and looked fun.
Did the unproject make you learn more because you were doing a different type of project.
Yea it made me learn more about fractions.

This unit was really easy for me.In the start i was confused and everything but after we learned more and we had so much homework from the purple book i got to learn it. I find adding and subtracting and multiplying fractions easy too. But i'am not so good in dividing fractions , i know how to do it but sometimes i get mixed up.

Did you like the unproject?
-Yes I kind of enjoyed it because it was really easy for me.

Did the unproject make you work harder than you usually would?
-No because i knew everything about adding and subtracting fractions which made it easy

What did you like best about the unproject?
-The best part for me was making the game because it was fun and easy to make.

What would you change about the next unproject?
-I would not change anything but i would add in a little more information.

Did the unproject make you learn more because you were doing a different type of project.
-No it didn't really make me learn more it just was like a review for me.

These are my notes for my test:

When dividing fractions you have to reverse the second fraction then times them.
If the fraction has a whole number you have to make it into an improper fraction.

When Multiplying fractions you just times them but if it has a whole number make it into a improper fraction.

How to Subtract fractions:If the denominator is the same you just subtract.
If the denominator isn't the same you have to find the lowest common denominator.
If there is a 1 whole number you leave the whole number and subtract the fractions.
If there are 2 whole numbers you subtract both whole numbers along with the fractions

To borrow you take one number away from the whole and add the denominater with the numerator to get the numerator.

Did you like the unproject.

No I didn't because i had so much other stuff to do that i had to do it the last minute and i go it done yesturday April 6. which was do on april 5 thurs.

Did the unproject make you work harder than you usually would?

well not really it just wasted my time just kidding. but i did learn my lesson, I really did. And it did kind of make work hard on it because it kept on bugging me that it wasn't completed.

What did you like best about the unproject?

I thought the best part was making the links and the new pages, because at first i was clueless what to do untill Jullie came to help me.
What would you change about the next unproject?
Did the unproject make you learn more because you were doing a different type of project.

Yes it made me learn more and understand. I'd make a big improvement for the next uproject by planning it and getting started on it.

Bob
This unit on fractions was difficult for me because there was so many steps for the different kind of fractions. For example subtracton frc., adding frc.Sometimes i'd mixed them up. I'd understand what to do but I get nervous whenever the tests and quizzs would come. So i guess I can say i did poorly on that. But this week we are learning dividing fractions and i'm actually working and doing the homewok to get some practise on that.

2007-04-06T00:41:00.000-05:00

This unit was doing alright with me. It was not to hard and not to easy it was just right. I learned quite a few things that i didn't learn in elementry. Like for subtracting I learned how to borrow numbers from a mix number, although i have problems sometimes on that. I have problems for dividing still because I wasnt there when he taught the class so i have to learn from someone FAST. Also multiplication, i still have to work on that. Adding and Subtracting are easy for me I have no problem with that.

Did you like the unproject?
Yeah, I did like the unproject and especially with abdul! Couldn't do it without him! Haha I also liked how you can learn something and still have fun on that unproject.

Did the unproject make you work harder than you usually would?
Actully yes it did. But i work harder then anything when I work on computer because thats what I mainly do at home anyways so i can just work on something and still chat on msn while working :D.

What did you like best about the unproject?
The thing i like best about the unproject was messing with the HTML , like putting songs and banners. But I could do better but then theres some HTML that dont work with it so I had to leave it out. But the graphicy stuff is just for fun, whats important is that we got the information needed.

What would you change about the next unproject?
I would change the quiz , the quiz was a bit difficult to make because you got one right answer, then you have to make up some other possibilities and its just hard cause its a smile question. So if i had the chance to i'd change the quiz and make like a game or something.

Did the unproject make you learn more because you were doing a different type of project?
No not really because i already knew more about Adding and Subtracting so it didnt really make much of a diffrence.

I found this unit on fractions quite easy, although I'm still having a bit of trouble on subtracting fractions and diving fractions. On subtracting fractions, I don't know how subtract with a fraction that has a whole number and on divding fractions as well.

Finding the LCD or lowest common denominator quite easy. I also find multiplying and adding fractions pretty easy as well.

In this unit I find the tests hard. Although I got good marks in some, I occasionally get lower mark.

Did you like the unproject? Well it was alright. It was sorta hard to make a good wikispace
Did the unproject make you work harder than you usually would? Not really. It was like the wikispace we had to make for our parents, so it wasn't really that hard for me.
What did you like best about the unproject? Putting in the fnishing touches. Like all the color and extra links.
What would you change about the next unproject? I would start a lot ealier so I can get the job done and try different ways to present my unproject.
Did the unproject make you learn more because you were doing a different type of project? I'd make a quiz on the topic instead.

The LCD was easy 4 me.I did most of the work that was given. When we started to do the division paart that messed me up and i still sorta have trouble with it. Overall this unit was okay

Did you like the unproject. -The unproject was alright I am just glad it is done
Did the unproject make you work harder than you usually would? -Yes, it did make me work harder cuz i had to some in early and get it done
What did you like best about the unproject? -The best part about the unproject is the finished product cuz atleast its done
What would you change about the next unproject? -I would change how it a was made i could have made it better.....
Did the unproject make you learn more because you were doing a different type of project. -Sorta i learnt how to use the computer better

SUBTRACTING FRACTIONS .

2007-03-12T21:29:00.000-05:00

When you want to subtract fractions that are a mixed number you should convert the mixed number into an improper fraction, then subtract them as fractions.Heres an example 5 1/8 - 2/3 = ? .. convert the mixed number into an improper fraction. which is 41/8 find the most common denominator and that is 24. your fraction now is 123/24. SINCE 8 x 3 = 24 and 41 x 3 = 123. The other fraction is 16/24 because 8 x 2 = 16 and 8 x 3 = 24. Then subtract 123 from 16 and that equals 107/24.. if you want to convert it back to a mixed number you have to see how much 24 goes into 107 . which is 4 times, then how much remains and that would be 11. mixed fraction is 4 11/24...
If the fractions aren't in a mixed number.. heres the way to do it.
2/3 - 3/5 = 10/15 = 9/15 = 1/15 .. multiply the denominators by each other ( 5 x 3 =15) .. then cross multiply 2 x 5 = 10 and 3 x 3 = 9 .. fraction is now 10/15 and 9/15 then subtract 10 from 9 and that gives you 1/15 ..
If the fractions have different denominators
1) Find the least common denominator.
2) Find the equivalent fraction using this denominator.
3) Subtract the fractions, if you could reduce then you should.

Adding Fractions for dummies Author abdul .s

2007-03-12T20:24:00.000-05:00

There are 3 Simple Steps to add fractions:

Step 1: Make sure the bottom numbers (the denominators) are the same

Step 2: Add the top numbers (the numerators). Put the answer over the the same denominator as in step 1

Step 3: Simplify the fraction.

Example 1:

1	+	1

4		4

Step 1. The bottom numbers are already the same. Go straight to step 2.

Step 2. Add the top numbers and put the answer over the same denominator:

1	+	1	=	1 + 1	=	2

4		4		4		4

Step 3. Simplify the fraction:

2	=	1

4		2

(If you are unsure of the last step see the equivalent fractions page)

Example 2:

1	+	1

3		6

Step 1. The bottom numbers are now different. We need to make them the same:

1	=	2

3		6

Step 2. Add the top numbers and put them over the same denominator:

2	+	1	=	2 + 1	=	3

6		6		6		6

Step 3. Simplify the fraction:

3	=	1

6		2

Adding Fractions with Different Denominators

To Add Fractions with different denominators:
Find the Lowest Common Denominator (LCD) of the fractions

Add in the new numbers to the fractions to have the LCD

Add the numerators of the fractions

Simplify the Fraction

Example: Find the Sum of 2/9 and 3/12
Determine the Greatest Common Factor of 9 and 12 which is 3

Either multiply the denominators and divide by the GCF (9*12=108, 108/3=36)

OR - Divide one of the denominators by the GCF and multiply the answer by the other denominator (9/3=3, 3*12=36)

Rename the fractions to use the Least Common Denominator(2/9=8/36, 3/12=9/36)

The result is 8/36 + 9/36

Add the numerators and put the sum over the LCD = 17/36

Simplify the fraction if possible. In this case it is not possible

Equivalent Fractions

2007-03-12T12:03:00.001-05:00

Equivalent Fractions are fractions that are equal or have the same value. They both represent the same pieces.

They are either a multiple or a divisor.

-This is like a multiple, you have a pie. Your sharing it with your best friend. So, each of you get 1/2 of the pie. The 2 pieces of the pie are too big for you two to eat. So, you went and cut the 2 pieces into half. Now you both have 2/4.
-To find a multiple of a fraction, you multiply both the numerator and the denominator by the same number.
-Example: 2/4 x 5/5 = 10/20

-This is a divisor, you have a pie. It was cut into 4 pieces. You and your friend are going to share it. So, you get 2/4 and he gets 2/4. You put your 2 pieces together and realize you have 1/2 of the whole pie.
-To find a divisor of a fraction, divide both the numerator and denominator by the same number.
-Example: 50/60 divide by 10/10 = 5/6

Improper fraction

2007-03-12T12:03:00.000-05:00

Definition: A fraction with a numerator larger than the denominator

How to convert a improper fraction to mixed
Step one: check how much the denominator can go into the numerator. Then put the whole number for the mixed as how many times the denominator can go into the numerator.
Step two:The remaining numbers are the numerator and the denominator stays the same.

Picture:

Proper Fractions

2007-03-10T13:22:00.000-06:00

Proper Fractions

Definition : A proper fraction is a fraction with a smaller numerator then denominator.

Names used in fractions:

numerator - is the number to the left of the line. In the fraction 7/8 the numerator is 7.

denominator - is the number to the right of the line. In the fraction 7/8 the denominator is 8.

Proportional Fractions - At the beginning of this page we defined the word fraction as a portion of the whole. We have shown that there is more than one way to write the portion that is half of the pizza. One half can be written as 4/8, 2/4 or 1/2. We say that these equivalent fractions are proportional fractions because they are the same portion of the pizza. Here are some different examples of proportional fractions using the integer bars. All of them are equivalent.

This unit (percentages) was alright, a little challenging, but good. Most of the work was easy. The hard thing was trying to place the fractions from the fraction lines to X.K.Y charts. >> I absolutely STUNK at doubling and reducing size. I know I did bad last term. xD

I found this unit pretty easy, i think the ratio tables were the easiest for me but i got confused by the xky charts.
I think i should start doing more of my homework to help me understand it a little more.
I also had trouble doubling the area of a shape, and i think doing those warm up things at the beginning helped me.
I think i understood the proportion word problems when i did them.

I think this unit was pretty cool, I learned a lots. The easiest thing for me was the part and total. The hardest thing for me was doing those xky charts. And I found out the white booklet a little tough.I think i did good in this term but i need to improve on doing my homework.

Cumulative Question 6

2007-02-09T08:35:00.000-06:00

(6) Jacob has a record of winning 2 boxing matches for every 5 he loses. If he had 49 matches during the last year, how many did he win?

This questioned was changed yesterday in class if no one can remember.

First you must do this:
Favourable Outcome
----------------------- (<-this meaning a fraction line)
Total Possible Outcomes

Out of every 7, Jacob wins 2. So... 2/7

Now we have to find out how many times he's won out of his 49 matches.

7 goes into 49 7 times.

There's your answer.

APRILP - CUMULATIVE QUESTION #1

2007-02-09T00:38:00.000-06:00

You have a notebook of 23 sheets of paper; and 3 of them are black. A page falls from your notebook; what is the probability it was a black sheet?

3/23
(3 is the favourable outcome and 23 is the total possible outcome)

3 divided by 23 = 0.13%

The probably it being a black sheet is 13%

Josh's Cumulative Question # 7

2007-02-08T22:35:00.000-06:00

Christina practices figure skating an average of15 hours per week.

Kayla practices figure skating an average of 1.5 hours for every hour Christina practices.

How many hours a week does Kayla practice?

Since Christina practices 15 hours a week and Kayla practices 1.5 hours (90 min.) for every hour Christina practices all you should have to do is multiply 90 x 15 = 1350 min. ( 22 hours and 30 min.)

Christina = 60 x 15 = 900 divided by 60 = 15 hours a week

Kayla = 90 x 15 = 1350 divided by 60 = 22 hours and 30 min. a week

I thought this unit was hard at the beginning. The easiest thing for me to understand was the ratio tables. The xky charts were difficult at first but I think I came around and got used to doing them. Doubling the area of a shape was confusing for me. I am getting better at it but still not perfect. I may still need some help in certain areas in math but I think I will get it over time.

2007-02-08T20:03:00.000-06:00

APRIL'S BOB and cumulative questions

(5)
What is 20% of 156?
to find this answer you divide 156 by 100 and multiply it by 20 to get 20% of 156
156 (divide) 100 = 1.56 X 20 = 31.2
31.2 = 20% of 156
the fraction would be
31.2/156 = 20/100

30 is 29% of what number?
divide 30 by 29 , then multiply that answer by 100
30 (divide) 29 = 1.03 X 100 = 103
the fraction would be
30/103 = 29/100

BOB

In this math unit I've learned alot even though there were times where I was so frustrated on what to divide and multiply and that stuff. I had a hard time with doubling the area of a shape I still dont get it that much right now but i'll learn on the way. The X K Y charts and the ratio tables were a bit comfusing at first but as i started working on them they became a piece of cake.

Qtypies's Question 3

2007-02-08T20:02:00.000-06:00

The police have cornered this criminal in a small 23 home community. If they have only 46 hours to find him, and they can fully search one house in 2 hours and 23 mintues, will they find him?

So first you want to change the time to one unit. So if you change it to minutes then 2 hours and 23 minutes will be 143 minutes and 46 hours would be 2760 minutes.

Math work:

converting 2 hours and 23 minutes to minutes

Converting 46 hours to minutes

60 x 46=2760

60 is 1 hour and 46 is how much time they have

Conclusion

Math work:

2760/143= 19.30( rounded 19)

no, the police won't find him. because there is 23 houses and in my answer above it calculates to 19.30(19) so they will only fully search 19 houses in 46 hours.

Please leave comments behind on what i did wrong and other things!

3) 44 is what percent of 62.

44 / 62 = .7096 * 100 = 70.96%

4) 55%of 26 is what number?

26 / 100 = 0.26 * 55 = 14.3%

Francis post for question 12

2007-02-08T19:00:00.000-06:00

(12) Dave interviewed a number of students in his school regarding their favorite ice cream. Dave claimed that exactly 40% of the 37 students interviewed liked vanilla the best. Is it possible to determine whether David's claim is correct? Why or why not?

40/100 14.8/37
40/100x37=14.8

It is not possible that David's claim is right because 40% equals to 14.8 out of 37 people and there cant be a person that is .8 .

At the beginning of the unit it was a little hard but after I understood it, it was all easy. I learnt how to use x k y charts because i've never heard of one before. The hardest part of this unit was learning how to double the area of a shape. I still have a few problems with it. The easiest part of this unit was solving word problems, because im good at x k y charts and the t charts. Overall I think i did pretty well on this unit.

(6) Jacob has a record of winning

2 boxing matches for every 5 he loses. If he had 49 matches during the last year, how many did he win?

answer:

He won 14 matches out of 49.

To get this answer you have to add the total number of matches. He won 2 and lost 5 so the total is seven. To figure out the answer you have to divide 7 by 49 which is 7. Then multiply 7 by 2 which is 14. That is your answer

During this math unit, there's been a lot of confusion for me. First of all, I had a hard time trying to understand that " funny tic-tac-toe looking thing " which was actually the X K Y chart. But then I started working on it a little more. Plus, my group members were always helping each other out so that made things a little easier. The easy part was working on the charts. The hard part would probably be doubling the area of a shape. I learned a lot in this unit.

As we did this unit it took me a long time to understand what we were learning. I learned how to use a X,K,Y chart and a ratio table and how to solve proportion word problems. I think the hardest part of this unit was how to double the area of a shape. I also found the white booklet was a bit easy as I started to understand what I was doing. Overall, I think I did a pretty good job in this unit.

I think this unit took a very long time to get through, but i learned a lot of things. The easiest thing for me was the part and total, and the x k y charts. The hardest thing was doubling the area of a shape without quadroupling it. I also found the white booklet a little hard. Overall, I'd say I did alright, but sometimes I didn't do my homeowork.

This unit was hard at the beginning, but once we worked on it. All of the work got easier and it made more sense to me. I would say that the blue booklet was the easiest thing out of this whole unit. The easiest thing in the blue booklet was the percents part and the page with the word problems on it. We learned how to make “xky” charts and “part and total” table; I find that the ratio table was the easiest to do. The white book was probably the hardest, but once I asked for help from people in my group it got easier and I finally knew what I was doing. I hope that I would do better in the next unit and term.

I think that this unit was hard,confusing and kept me learning all at the same time. I struggled for most part of the unit. The easiest thing of this unit was the House Proportions project or unit. The hardest part was the "XKY" charts and the ratio tables because they were confusing at first. I think that on the "XKY" charts and the ratio tables because I was doing good on that. For me on the unit I think I have to better on this unit and the others to come. I think that I did well in this unit, I hope... .

In this unit I learned about "xky charts", and "ratio tables".

The parts that felt easy for me to do on this unit was the assignments in the blue booklet. I did well on the percent parts of this booklet where we had to shade in the percent.

The parts that felt hard for me to do on this unit was on some parts of the white booklet and the "part and total charts". Thanks to the help of some students that I got the hang of it.

In the next unit I'll try doing better and try to finish my assignments before the next math class.

During this unit I learned how to make xky charts and proportion tables. i first found this unit hard and complicated to follow because there were so many things to learn, but when mr h explained things step-by-step i got a better understandings of it.

My favorite part of this unit are the xky charts; they seemed a little easier for me to do because all the information is there to see. also i enjoyed doing the blue booklet mr h gave us. it was easy and fun. it wasnt a pain to do it for homework. xD

i found the white booklet pretty hard. some of the questions were simple and easy while others were complicated and long. also a lot of the questions had something to do about "looking for lenghts" and i wasnt sure how to that either. i asked for help and i eventualy started to get a hang of it.

Proportion Unit

I learned a lot during this unit. At first, I had no idea why do we have to use ratio tables and "x" "k" "y" charts. I learned that these two strategies helped to solve problems with no happy numbers :(
These two strategies are exactly the same as answering a problem with two equivalent fractions. The numbers are all the same it's just where you put them. Overall this unit was pretty easy.

Question 5:
If 25 DVD Rom cost $14.50, calculate the cost of 11 DVD Rom

I solved it using word ratios. 11 DVDs would cost $126.
DVDs 25 x.44 11
Cost $14.50 x.44 $126

Question 6:
If 5 tickets for a play cost $40, calculate the cost of:
6 tickets
14 tickets
20 tickets

I also solved this question using a word ratio. 6 tickets would cost $48, 15 would cost $112, and 20 would cost $160

5X8 = 40
6X8 = 48
14X8 = 112
20X8 = 160

We also learnt a bit about an assignment coming up that we will be doing on the internet later. Its a sheet of questions we'll have to answer later on.

Question 1 What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your definition.

-A percent is an equivalent fraction out of 100.

-Percents can be converted into fractions, decimals or ratios.

-% is the symbol used to represent percents

-to convert a fraction into a percent, you have to divide the numerator by the denominator 1/4 is the fraction (1\4=0.25) then you have to multiply the answer by 100 (0.25x100=25%)

Question 2 How are three fifths (3/5), 3:2, 60% and 0.6 all the same?

Question 3 Show 3 different ways to find 35% of 80

Question 4 Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review (what the post was talking about...yes you have to read the post and why others should read the post) Hint: In the side bar there are links to other schools. Three of them have done work on percentages! I left my comment at https://www2.blogger.com/comment.g?blogID=33406999&postID=116474431867734886 .It was very easy to understand and it explained a lot about percents. Someone who didn't know anything about percents would know what they were talking about after they read this post.

Question 5 The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms. Lowrey's class met their reading goal for the month. Ms. Stanzi said that a greater number of her students met their reading goal. Could Ms. Stanzi be correct?
Yes, Ms Stanzi could be correct because the principle did not say how many children were in each class. It would depend on how many students were in each class.

Let's say Ms Stanzi had 40 students and Ms Lowrey had 20.

20 of Ms Stanzi's students met their reading goal. (40/2=20)
11 of Ms Lowrey's students met their reading goal. (20/100=0.2x55=11)

In this case Ms Stanzi would be correct.

Question 6 Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means, solve it.

a)16 is 40% of what number?

b)What is 120% of 30?

I have left a comment at http://linden8z.blogspot.com/2006/12/review-of-percent.html, the person who made the post was talking about the three ways you can get a percent. I think others should read the post because it is organized nicley and the person seems to know what they are talking about.

Question #5

The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

I think that Ms. Stanzi could be correct because it did not say how many students were in Ms. Lowrey's class, and you would need the amount of students are in her class to figure it out.

Question #6

Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.
a) 16 is 40% of what number?
b) What is 120% of 30?

16 is 40% of what number?

We wouldn't really know because she didn't exactly say how much people are in her class, but then theres a chance she could be right if there were more kids in her class. If Ms. Stanzi was right that would mean there would be 60 people in her class and only 40 in Ms. Lowrey's class. If you divide 60 from 100 then multiply by 50 it would give you 30. For Ms. Lowrey's class, if you divide 20 from 100 then multiply by it 55 it would give you 11. Therefore Ms. Stanzi is right. If it was the other way around then Ms. Stanzi would be wrong.

Question 1)
What is a good definition of Percent?

One is It is a equivalent number out of 100.
Two is It is part of a whole

Three is The symbol of a fraction is %

2.)How are three fifths(3/5), 3:2, 60% all the same?

3/5 , 3:2, 60%, and 0.6 are the same because they are all equivalent

0.6 x 100= 60% that is a picture

3/5 = 0.6 How? divide the Numerator by the denominator

3.) Show 3 different ways to find 35% of 80?

one way is... 35 divided by 100= 0.35

0.8 x 80= 28

The second way is... 80 divided by 100= 0.8

0.8 x 35= 2

4.) Find a link to blogs that deal with percentages. leave a comment behind and add the link with a review.

http://linden8m.blogspot.com/ if u need help on converting, or decimals, percents or ratios that the site to go to.

5.) The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms. Stanzi's class has 50% of children who seen their ready goal. 50% is half of a 100%.

Ms. Lowrey's class has a 55% of children that have seen their reading goal for the month. 55% is not half of 100%. What i did was i divided 55 by 2 and it equaled to 27.5 but i think Ms. Stanzi's guess was right.

50% out of 100

6.A)Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

40 divided by 100 = 0.40

4 x 16 = 6.4

6.B) What is 120% of 30?

30 divided by 10 = 33 then i x 12 = 36

P.S) I couldn't get any of the Bubble Share and the Gliffy to work i tried but my computer wouldn't let me upload anything so i couldn't do it on those sites you a signed us with so i did it on here. Sorry

Question 2
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.

They are equivalents, meaning they equal the same thing. An equivalent of 3/5 is 60/100. 3:2 is 3/5 except in a different form. o.6 multiplied by 100 equals 60. In the end they all equal 60/100.

Miss Stanzi could be correct. her thought would only be right if she had a greater number of students in her class than Miss Lowery's. For instance, if Miss Stanzi had 30 children in her class 15 people would have accomplished the goal. If Miss Lowery had 25 only 13 students would have accomplished it.

I think this is a really good site because it deals with percents, decimals, ratios, and fractions. They also have pictures to help you understand what they are talking about. I think this site could really help you if your confused about something.

Question 5

The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms. Stanzi could be correct. She could be right if the number of students in her class is greater than the number in Ms. Lowrey's. If Ms. Stanzi has 50 kids in her class then 25 of them {50%} met their reading goal. If Ms. Lowrey has 40 kids in her class then 22 of them {55%} met their reading goal. But if they both have the same number of kids in their class Ms. Stanzi would be wrong.

Question 6

Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?

You divide 16 by 40 = 0.4 x 100 = 40

b) What is 120% of 30?

You go 30 divided by 10 = 3 or 10%

3 x 12 = 36 or 120% of 30

Percents can also be converted into a fraction, decimal or into a ratio.

3/5, 3:2, 60% and 0.6 are the same because they are all equivalents.

Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not?

This answer all depends on how many students are in their class.

But let's just say that there are 45 students in Ms. Stanzi's class and 40 students in Ms. Lowery's class.

There may be 55% of Ms. Lowrey's class that met their reading goal but that doesn't mean there are more students in her class.

Question 6
Use a hundred grid (unit square) to illustrate the following question. Once you have explained and illustrated what the means solve it.

Question 2:
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.

They are equivalent and are the same
subtract 5-3 from the fraction 3/5 and gives you the ratio 3:2
divide 3/5 and it would give you the decimal 0.6
fraction of 3/5 to 60 %
How I got this; Since the circle is 100 percent and I need to get 60%. I divided 100 by 5 and I got 20 %, so I put 20% in each separated piece and put the percentage of each side. I added the left side and i got 60% and then when i added the right side i got 40%.

I think this site is a really good that deals with percentages. They talked about reducing, cross multiplying, and ratios. The posts were well done. :)

Question 5:
The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ok , lets just say that Ms.Stanzi has more students in her class than Ms.Lowrey's class. So like Ms. Stanzi might have had like about maybe say 50 students and Ms. Lowrey had 40 students in her class.

Ms. Stanzi's class : 50% of 50 - 50/2=25
Ms. Lowrey's class : 55% of 40 - 40/100=0.4x55=22

So there were more students in Ms.Stanzi's class that met their reading goal for the month.!

Question 1
What is a good definition of percent? You should use words, symbols, pictures and numerical examples in your definition.

Question 2
How are three fifths (3/5), 3:2, 60% and o,6 the same? Use pictures and words to show your answer.

Three fifths, 3:2, 60% and o.6 are the same because they all equal the same thing.
The fraction three fifths can be divided. 3 divided by 5 = 0.6.
0.6 x 100 = 60. Which is 60 percent. Three fifths can also be turned
into a ratio.

Question 3
Show 3 different ways to find 35% of 80.

80 divided by 100 = 0.8
0.8 x 35 = 28
o.8/1 = 28/100

80 divided by 10 = 8

8 x 3 = 24

8/10 = 24/80

80 divided by 2 = 40

40 divided by 2 = 20

20/80 = 40/100

This is a link explaing what a percentage is and how a percent is a fraction. Great use of pictures, understandable instructions and good humor. xD

Ms. Stanzi's class has 50% of children who met their ready goal. 50% is half of a 100%.

Ms. Lowrey's class has 55% of children met their reading goal for the month. 55% is well, not half of 100.

If we don't know how many students met their reading goal we will never know if Ms. Stanzi's theory is correct. Althought you can't really say that she's wrong either.

Question 6

Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?

40 divided by 16 = 2.5
2.5 x 100 = 250
2.5/1 = 16/250

b) What is 120% of 30?

30 divided by 120 = 0.25
o.25 x 100 = 25

Don't ask me why the font is all funny looking. I can't fix it. I already tired. I can't use Bubbleshare on my computer because the html code won't work. I just used a lot of pics that I made from paint.

Question 1.

What is a good definition of percent?

A good defintion for percent is and equivalent fraction out of 100 or when you are finding a percent just make happy number like 10 or 100 instead of 62.5.

Question 2.

How are three fifths (3/5), 3:2, 60%, and 0.6 all the same?

Question 3.

show three different ways to find 35% of 80.

1)80 divided by 100 equals 0.8 times 35 equals 28

2)35 divided by 100 equals 0.35 times 80 equals 28

3)35 divided by 10 equals 0.35 times 8 equals 24
8 divided by 2 equals 4+24 =28

Question 4.
Find a link to blogs to deal with percentages. Leave comments behind and add links with a review.

Question 5
The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Ms Stanzi's class has more people because her class can have 40 kids and the other class can have 35 kids.

40 divided by 2 equals 20
35 divided by 2 equals 17.5
35 times 0.05 equals to 1.6
17.5 plus 1.6 equals 19.1

There could be any number of people as long Ms Stanzi's class has more people.
Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?
b) What is 120% of 30?

answer for
a)

b)30 divided by 100 = 0.3 times 120 = 36

Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not. Ms. Stanzi's could be correct because maybe she has 40 people in her class and 20 of them is 50%. Ms Lowrey's class could of have only 30 people in her class and 55% of that is 16. That means Ms Stanzi could of been right but we don't really know how many people she has in her class or Ms Lowrey.Question 6

Today in class, we got 10 x 10 Grids and 3 big pieces of paper and we folded the 3 big pieces into three "hot dog" folds.

then we connected them to each other, and then we cut out 24 square pieces of grid paper and glued them onto the three pieces of paper.

First we glued 1 square box to the piece of paper on wrote 100% , then we glued another piece onto the the paper and wrote 1%, then we glued two boxes as 150% and glued one as 1/4 or 0.25%.

then we glued another piece to to the second sheet and wrote down:

under neath the box.

100 divided by 100 = 1

100 or infinte 100 = 1%

100 equal groups = 1%

then in the second box we put down:

500 divided by 100 = 5 or 1%

1/500 = 5/500

then in the next side we put down:

100 divided by 10 = 10%

10 or infinte 100 = 10%

10 equal groups = 10%

then in the second box we put down:

500 divided by 10 = 50 or 10%

10% = 50

1 x 10% = 10%

1 x 50 = 50%

1/10 = 10/100 = 50/500

Then we had to that for 5% , 12% , 86% , 20% , 70% and 5%

Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

This could be right or wrong. It all depends on the number of people in the class.

Pretend that Ms.Stanzi's class has 40 people and Ms.Lowrey's class has 30 people.

Well 50% of 40 (40/2=20) is 20 while 55% of 30 (30/100x55=16.5) is about 17.

So more people in Ms.Stanzi's class met the goal.

Now pretend that Ms.Stanzi's class has 30 people and Ms.Lowrey's class has 40 people.

Well 50% of 30 (30/2=15) is 15 while 55% of 40 (40/100x55=22) is 22.

Now more people in Ms.Lowrey's class met the goal.

Today in class the first thing we did was look over Abduls Growing Post.

Then we went over yesterday's homework which was Find 3 different ways to show
35% of 80
60% of 180
90% of 150

Notes
1/100 means divided by 100 or 100 equals groups or 1%

<- 50% is 1/2 of 100. Any number divided by 2 is 50% 10% =10/100 or 10 out of 100 =1/10 or 1 part out of 10 10% is making 10 equal groups or dividing by 10

25%

25 out of 100
25/100 ---> simplifies to1/4

25% = 20 (80 divide 4)
10%= 8 (80 divided 10
35 28

In class work/homework
find 3 different ways to find, show on grid paper
35% of 120
55% of 90
40% of 25
65% of 180
15% of 40

70% of 256 256\100=2.56*70=170.2 70\100=0.7*256=170.2

Mr.H told us to find 30% of 70 three different ways:

30\100=o.3*70=21

70\100=0.7*30=21

30/100 -->0.3/1*70=21

10/100=1/10=7/70

10%=7
10%=7
10%=7
----------
30%=21

For homework, we have to find three different ways to show

35% of 80
80\100=0.8*35=28
35\100=o.35*80=28
35/100=0.35/1*80=28

60% of 180
60\100=0.6*180=108
180\100=1.8*60=108
60/100=0.6/1*180=108

90% of 150
90\100=0.9*150=135

2006-12-07T12:09:00.000-06:00

Today in class we went over yesterdays homework which was.....

400 and 162
we had to figure out the percents out of 400 and 162.

The numbers were :

1%= 400\100*1=4
5%= 400\100*5= 20
10%
30%
65%
75%
You divide 400 by 100, then multiply the asnwer by the percent.

Mr.H gave us a question...

What does 40% mean?
we came up with....-40/100
-2/5 is 40%
-part of a whole
and some more ...

then he told us to write down
When you are finding out a % you are just making happy numbers out of 100 is easier to compare then out of 62.5 :)!

then we did the following ....

------ ------
100 400

1% 1/100 ---------> 4/400
5% 5/100 --------> 20/400
10% 10/100 -------> 40/400
30% 30/100 ------> 120/400
65% 65/100 ------->160/400
75% 75/100 ------->220/400

Then he said " what is 45% of 60?"

this is how we did it ..

60\100-0.6*45=27
35% 45\100*60=27

part - 45% ?
-------- = -----
whole - 100 60 <--- 60\100*45
0.6
-------
1
45 45 0.45
----- = ----- ------ = ------ <---- decimal
100 60 100 1

Another question was 32% of 87?
(32 is bad) (87 is good)

32% ?
----- = -----
100 87
Y
87\100=0.87

Our homework questions were what is...

45% of 60?

21% of 78?

35% of 18?

91% of 210?

55% of 370?

12% of 125?

70% of 256?

and that's what we did in class , i hope you like it :)

MYRH-RYNN WILL BE THE NEXT SCRIBE FOR DECEMBER 7th :)

( some of the things that i did with fractions and stuff didnt really work out , so if you just move then to the side a bit when you are reading this then it will make sense ... sorry:( )

Your First Growing Post

2006-12-06T20:40:00.001-06:00

It is almost time for Winter Break and this is an important computer assignment. It is called a growing post. It is called a growing post because you create one post and add to it everyday. This assignment can be done at the last minute or it can be done a few questions at a time over the two weeks.

Remember you only create one post. You then edit it as you add more information.

Title (Place Name Here) Percentage Growing Post

Question 1
What is a good definition of percent? You should use words symbols, pictures and numerical examples in your definition. (suggestion gliffy is an excellent tool for adding detail to your definition.)

Question 2
How are three fifths (3/5), 3:2, 60% and 0.6 all the same? Use pictures and words to show your answer.

Question 3
Show 3 different ways to find 35% of 80. (bubbleshare is an excellent tool to animate the many different ways of finding these answer).

Question 4
Find a link to blogs that deal with percentages. Leave a comment behind and add the link with a review (What the post was talking about....yes you have to read the post and why others should read the post) Hint In the side bar there are links to other schools. Three of them have done work on percentages!

Question 5
The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.

Question 6
Use a hundred grid (unit square) to illustrate the following questions. Once you have explained and illustrated what the question means solve it.

a) 16 is 40% of what number?
b) What is 120% of 30?

Scribe Post For December 4th

2006-12-05T20:53:00.000-06:00

December 4th

First thing we did was convert 0.65 and 5:2 (Five to two.) The answers were 65%, 65/100, 65:35 (100 - 65), 5/7, 0.714, and 71.4%

Yesterday we had made a list of all the things we knew about Percents. But first we had to figure out how to make this shape larger or smaller. This was homework due on the 5th.

We also made a web on what we knew about percents. It had to include pictorial items, numbers, words, and symbols, for symbols you'd obviously put %. Here are some examples:
If you cannot read those words get some binoculars! (I dare you to click this.)

If you'd like to see some more things about percents check out: http://en.wikipedia.org/wiki/Percentage

Mr. Harbeck gave use some questions:

What does 50% mean to you?
What does 25% mean to you?
What does 10% mean to you?

Everyone answered indiviudally and a few people were picked, from Mr.Harbeck's card deck with our names, to give some answers. The only wrong answer is no answer!

Homework was to find 1%
10%
25%
75% and
15% of 85 and 300.

Math Pretest

Convert the following values so that you can place them on the number line below. Show all your work.

0.175

55%

3:10

15/51

9:3

How could you determine whether the average of these numbers is greater than 10 or less than 10 without actually computing the average. Explain how you decided the average was more than or less than 10.

Today in class we had three things to do.

1. Make a T-chart for all of those numbers we converted for the number line.

2. Fix our number line.

3. The homework that was on the overhead.

For the T-chart {Assignment 2}

On the left side you put whatever you converted your numbers to {for the giant number line}. So if you converted all of them into percents that is what you would put on the left side. It's the same for fractions, decimals, and ratios.

On the right side you put the raw value. It's what the number was before you converted it.

What you had to do on the number line was to put markers.

If you did it in percent you would do 10% 20% etc. Same for fractions and ratios. Then put your numbers in between them.

This is the homework:

Equivalent Assignment 3

1. Convert the following percents into decimals, fractions and ratios. Then put them on a number line.

35.5% 12.6%1.67% 93.6% 48%2.

Convert the following decimals into percents, fractions and ratios. Then put them on a number line.

0.23 0.906 0.078 0.65 0.10643.

Convert the following ratios into fractions, decimals, and percents. Then put them in a number line.

1:7 4:5 9:56 7:3 10:14.

Convert the following fractions to decimals, percents and ratios. Then put them on a number line.

8/9 4/7 12/17 3/8 8/21

Personal reflection.

What is the easiest conversion for you to do in this equivalent unit? Why?

What is the hardest conversion to do in this unit. Why? What makes this conversion hard for you?

Choose 3 values to convert to practice what you find difficult. Practice makes perfect.

The next scribe will be: Allan

APRIL'S SCRIBE POST
for november 22/06

Yesterday in class we did an Equivalents assignment on a big piece of graph paper. We had to place the following values below on a numberline with a group.

In my group (Me, April P. Josh and Jesse.) we converted the values into percents. We then put those percents also showing our work in numerical order from smallest to largest with its equivalent value. We then put the values on the numberline in numerical order, like we had on our seperate piece of paper.

Converting the values to percents.
50% ---- already a percent
3/4 ---- 3/4 - 3 divide 4= 0.75 x 100 = 75%
2:3 ---- 2:3=N/D - N=2 - D=2+3 = 2/5 - 2 divide 5= 0.4 x 100 = 40%
5/6 ---- 5/6 - 5 divide 6 = 0.83 x 100 = 83%
37.5% ---- already a percent
o.7 ---- 0.7 x 100 = 70%
9/10 ---- 9/10 - 9 divide 10 =0.9 x 100 = 90%
7:5 ---- 7:5=N/D - N=7 - D=7+5 = 7/12 - 7 divide 12 =0.58 x 100 = 58%
95.8% ---- already a percent
0.08 ---- 0.08 x 100 = 8%
17/40 ---- 17/40 - 17 divide 40 = 0.42 x 100 = 42%
0.484 ---- 0.484 x 100 = 48.4%
0.82 ---- 0.82 x 100 = 82%
17/200 ---- 17/200 - 17 divide 200 = 0.085 x 100 = 8.5%
80:30 ---- 80:30=N/D - N=80 - D=80+30 =80/110 - 80 divide 110 = 0.72 x 100 = 72% 29/47 ---- 29/47 - 29 divide 47 = 0.61 x 100 = 61%
66:34 ---- 66:34=N/D - N=66 - D=66+34 = 66/100 - 66 divide 100=0.66 x 100= 66%
80/108 ---- 80/108 - 80 divide 108 = 0.74 x 100= 74%
77:44 ---- 77:44=N/D - N=77 - D=77+44 = 77/121 - 77 divide 121 = 0.63 x 100 = 63%
18/92 ---- 18/92 - 18 divide 92 =0.19 x 100 = 19%

Values in Numerical Order
0.08, 17/200, 18/92, 37.5%, 2:3, 17/40, 0.484, 50%, 7:5, 29/47, 77:44, 66:34, 0.7, 80:30, 80/108, 3/4, 0.82, 5/6, 9/10, 95.8%
