Apparently I am supposed to choose one of the ratios I just did and show it in ...

Ratio - 3 : 12

Ratio Notation - three to twelve or Blue to all

Fraction - 3 / 12 or Blue / all

Decimal - 0.25

Percent - 25 %

My three question's are ..

1) If I double the amount of crayons I have then what will the ratio of Blue, Red, Green to all be.

2) What would the percent be of the ratio 7 : 140.

3) What is the decimal answer for 9 : 58.

What Did you get wrong on the Test.. How can you improve...

1) Most of my faults were because i did not convert the ratios to there lowest terms.

The reason why i had trouble with this was because Mr.Harbeck told us to only convert it to lowest terms if the question said to and because of that I did not convert it unless it said to.

2) The only question i had a real problem's with was # 12, 13, and 14.

In a group of 84 students surveyed, the ratio of student preferenceis seven oatmeal eaters to four granola eaters to three toasted O eaters.

12. Of the 84 students, how many prefur oatmeal.

13. Of the 84students, how many prefur granola.

14. what percent ( to one decimal place ) of the group prefurs Toasted O's .

Another Question that gave me trouble was ...

Write each ratio in lowest terms,

8 : 32 ~~~~

10 : 80 ~~~~

5 : 125 ~~~~

18 : 27 ~~~~
