### BOB - Proportional Reasoning

What i found easy about this unit was to finish the activities in the bluebooklets which were also aobut Proportional Reasoning, but in shapes and numberlines. What i found to be the most difficult was the word problems because they had some complicated stuff. I say this unit in Proportional Reasoning has taught me how to solve alot of problems in muliple ways, which may come in handy in the near future.

### Nicole's Culmulative Review Question #1

### question # 5 in cumulative question....

comment if i made some mistakes.. thnx... :D

-rivka cabalquinto 8-17

### Cumulative ; Question Number 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?

David is INCORRECT ! 14.8 Students like vanilla ice-cream. It is not possible to determine David's claim you can't have a decimal of a person. View BubbleShare for explanation.

### Question 11 Alexm

(11)Is taking 10% off a given item and then an additional 40% off the reduced price the same as taking 50% off the original price? Why or why not.

steps..................

-Choose a number you can easily play with... i chose ''100''

-10% off the original price(100) = 90

-My question; what is 40% of 90 = 40 "divide" 100 = 0.4 x 90 = 36

**answer: NO, it is not 50% when you do this because you get the 40% of the 90 making it 36.**

### Question 7 - Cu-mulative Question

1.5 (hours for every hour christina practices) x 15(hours per week) = number of hours kayla practiced. In this case, lets say christina practiced for 1 week which equals 15 hours. So... Kayla practices 1.5 hours for every hour christina practices.

1.5 x 15 = 22.5

kayla practices 22.5 hours in one week.

### Question#9 : Cumulative Review Questions =)

**Question no. 9 /.**

» 2,5,7,8,3,6,4,5,1

» 12,4,16,22,19,4

» 78,45,45,78,60,75

**(9)**Find the mean, median, and mode of the following sets of numbers.» 2,5,7,8,3,6,4,5,1

» 12,4,16,22,19,4

» 78,45,45,78,60,75

__Mean__= Average

__Median__= Middle

__Mode__= Most Common

Good luck on our TEST :)

### BOB-Proportional Reasoning

*When the first time I heard proportion, I thought that it was hard. At the first time we work on it I really thought I can't do it because I didn't know how to do it,but when Mr. Harbeck teach us the precious*

*"XKY CHART,the unstoppable "RATIO TABLE", and last but not the least the prestigious "EQUIVALENT CHART".When I first saw the questions and the problem of the blue book I thought that i can't answer anything but when we learn that three wonderful solution i can answer all of that horrible and scary questions. The hardest part was when I had to made rectangles.I learn more in this topic and I really learned about the 3 solution. In the most of time I really used XKY CHART because i really think that it's easy.Sometime i find many hard question on it.*

I think the easiest thing i did was the white paper and the hardest was the double the size of the shape.i hope i can pass the test now that i understand how to do the proportions and ratio...

### BOB - Proportional Reasoning

During this unit, I’ve learned multiple things about proportions and ratios. When we first got the blue booklet, I thought that it would have been difficult to do; the fact that I didn’t understand much about it. As time passed, I’ve learned how to use XKY charts, ratio tables, and equivalent fractions to solve problems. I also found proportions easier than I thought.

What I found easy was trying to complete the shapes in our blue booklet so that it is equivalent to the fraction given. What I found hard was reducing and enlarging the shape (like the one on the quiz) because it confused me a whole lot. This unit has taught me a lot on how to use these strategies to solve some problems in real life.

**proportional reasoning??? well, at first i thought its gonna be hard. but when mr.h gave us a blue booklet, and taught us how to solve the problems from the blue booklet, i realized that its not that hard. and yeah, i learned lots of things from this term. and i learned three ways in solving some problems like equivalent fraction, x k y chart and ration table. x k y chart and ratio table was kind of confusing but i still use it in solving problems. oh yeah, i was also confused in word problems, because i really dont know how to solve it like the one from the test:D.. the easiest part that we did is doing the blue booklet and the most difficult part is when we were learning about word problems... i really hope that i really did a great job in this term. im expecting that i will learn more things in the next term...**

### Andrea's B.O.B =)

__Proportion:__The first time I heard that word, I thought it was hard to figure out. But when the class finished the unit, I was glad that I was wrong. It's really easy to do if you fully understand everything Mr. H had said. All I did was I payed attention. At the end, I didn't have any trouble on answering word problems.

And that's the best part. I thought word problems was going to be hard, because some word problems are long. But Mr. H was right, if you can read, then you'll be able to answer the problem. Now, doing word problems became easy, whether in equivalent fractions, ratio tables and XKY forms. But I guess I got used to the 1st way, equivalent fractions. So I often used that one.

BUT, I find the decreasing-increasing-the-original-size part really confusing. And too bad, that is a part of the quiz/test. :'(

In this unit, I learned a lot, and I hope to learn more next term!

*At first, I thought that learning Proportional Reasoning was hard. But when we started doing the blue booklet, I found out that it was easy. Well, some of them were easy and some of them weren’t. I learned a lot of things this term. For me, the easiest part was solving the word problems using the x k y, ratio table and the 1 other way. The hardest part was enlarging and decreasing the original size (just like the quiz). I think that the x k y chart and the 2 other ways to solve the questions were easy to do. I’m expecting to learn a lot more about something next term.*

### BOB-Proportional Reasoning

After learning how to use ratio tables, XKY charts, and equivalent fractions to solve problems. I noticed that these questions weren't that hard. I think the more difficult part about proportional reasoning is not knowing which numbers go where and which chart to use. This unit have taught me a lot about how to use these strategies in real life.
