(Yes I know this is VVVVVVVVVVVVEEEEEEEEEEEEERRRRRRRRRRRRRYYYYYYYYY late, but I need it for my portfolio! =D)

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

Wiki thing

Mr. H
I went in at lunch and finished all of the question and answers but when i cheeked it at home its was all screwed up so it would be kool if u can fix that for me cuz i dont no what happened.

wes

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.

Bob

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

(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

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

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

Bob

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.

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

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!

Kimmie's Post for Question 5

Question 5 number 3 and 4

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

(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.

abduls question thingy

(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.

BOB Proportion Reasoning

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.

BOB

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.

BOB

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... .

-Chris

BOB .!

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.

Well for math i thought i did okAY. i COULD' VE DONE BETTER. bUT I ALSO THOGHT I'VE LEANED ALOT. iN CLASS I ALWAYS TRY MY BEST AND TRY TO UNDERSTAND. THE LAST QUIZ THAT WE GOT I THINK I DID PRETTY WELL ON THAT . aT THE BEGINNING OF THIS UNIT IT WAS HARD FOR ME TO GET USE TO IT BUT NOW I THINK I GET. BUT I STIL NEED HELP.

BOBSTER

I think this unit was a little too long. I think that I did good for the most part of this unit. The easiest thing in this unit was the blue booklet.The hardest thing was learning how to use the "XKY" and the "Part Total" charts but once I learned it, it wasn't so hard. I think that I am doing well this term and I hope to keep it up.

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.

amalia's 5 questions

Today in class Mr. H gave the class a sheet of paper with 20 math problems. Frances and i had volunteerd to do at least 5 different problems.


question 7.
David read 40 pages of a book in 50 minutes. How many pages should he be able to read in 80 minutes?
Well the answer i got and solved it goes like this, So what i did was that I had divided 50
pages 40 x 80 / 40 = 1.25 x 80 = 100.
_____ = / _______
minutes 50 100


Questoin 17.
If three apples cost 29cents , how much do 45 apples cost?

Well i solved the way i had answer goe like this. How i got this answer is by dividing 29/3=
9.6 x 45 = 4.35
apples 3 45
_____ = _______ So i think that the apples would cost
cost 29 4.35 $4.35.


Question 16.

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.

BoBby lee

I learned a lot of stuff this term. I learned ratios,percents,decimals and x k y charts and porportion table.I found nothing hard because i listen so much ,but i complain alot.I found that every thing easy once i started to get it.I liked using x k y charts and porportion charts. I hated all of the homwork and thats it. I like math its better than la, social and every other coarse.

BOB

I learned a lot of things threw out this unit. What i liked about this unit is making the p/t charts. The hard thing was doing the x,k,y charts because i still have a little trouble. But the hardest thing was where you had to times is by 2 but instead people times it by 4.

In the next unit i will try harder and listen and finish my homework.

MR H

I think that this unit was a long stretch for my mind. I think that I struggle for the most part of this unit. The easiest thing in this unit was the number lines in the blue booklet and the shading in the percent. The hardest part of this unit was learning how to use the "XKY" charts but now I know understnad how to do them. I think that I really have to try a bit harder. For me that how my unit went...i hope that I do better for the next unit.
