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 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.

This questioned was changed yesterday in class if no one can remember.
First you must do this:
----------------------- (<-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.
(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%

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.
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
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 .

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.
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.

2. If $24 worth of fertilizer covers 5,000 square feet, then how much would it cost to cover 30,000 square feet?
3. If a chain link fence costs $180 for 20 feet installed, how much would it cost to install 300 feet?
4. The scale on a map is 1 inch equals 5 feet. What is the distance between two points on the map that are 8 1/2 inches apart on the map?
5. A $4 sales tax is charged for a $50 purchase. At this rate, what is the sales tax for a $1200 purchase?
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.
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
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.
If it takes 1 cup of flower to make 6 cookies, how much many cookies can you make with 6cups of flower?

Audio Jeannie tajes inventory of her closet and discovers that she has 8 shirts for ever pair of jeans. If she has 4 shirts how many pairs of jeans does she have?
shirts 8 4
______ =____ = ___ This is the answer that i got.
Jeans 5 20
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.
dun... dun... dun...
I think that this unit was a long stretch for my mind. 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.
In the next unit i will try harder and listen and finish my homework.
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.
