My 3 Part to Part Ratios :

1) Blue to Yellow - 3:4

2) Red to Pink - 12:5

3) Green to Orange - 6:3

My 2 Part to Whole Ratios :

1) Blue to total 3:33

2) Pink to total 5:33

My 2 Part to Part to Part Ratios :

1) Pink to Blue to Yellow - 5:3:4

2)Green to Orange to Red - 6:3:12

The Ratio I choose is Blue to Yellow :

Ratio Notation - Blue to Yellow is 3:4

Fraction - 3/4

Decimal - 0.75

Percent - 75%

How to make an equivalent Fraction :

Equivalent fraction is like another word for equal fractions. In my diagram here it shows that the original fraction the numerator is 3 and I multiplyed it by 2 to get 6, so whatever you do to the numerator you HAVE to do the same to the denomenator so I multiplyed the denomenator and I got 8 because the original was 4.

Equivalent fraction is like another word for equal fractions. In my diagram here it shows that the original fraction the numerator is 4 and I divided it by 2 to get 2, so whatever you do to the numerator you HAVE to do the same to the denomenator so I divided by 2 the denomenator and I got 3 because the original was 6.

PROBLEMS !! :

1) What would the decimal, Fraction and percent be for yellow to blue ratio ?

2) What would the Orange to White to Black ratio be ?

3) Write the ratio for Orange to total then write it in lowest terms.

Some mistakes I got wrong on MY test were :

1) I forgot to write the answer in the lowest terms.

2) I didnt show my work.

3) I didnt get the write percentage.

Examples and my mistakes :

1) For question 3 I put D which was 2:4 which was wrong because I didnt do it in lowest terms, the answer was B 1:2.

2) For questions 17 and 18 I just wrote down the answer, I didnt show my work like how I got the answers.

3) For question 14 the way i got the percent was totally wrong the right way was alot more different.

How I can remember in Future Tests :

1) I can remember writing in the lowest terms by reasding the question more carefully.

2) I can remember showing my work by instead of doing my work on a scarp piece of paper I can just do it on my test paper.

3)For getting the percent I would use a ratio table to get the correct percent.

Problems :

1) In a student election Carol gets 40% of the votes. If there were 525 votes cast, how many votes did Carol get ?

2) 5 students were running for student council president. Of 100 students polled, 50 chose mike, 9 chose Patricia, 24 chose Brian, and the rest chose Karen. What is the ratio of votes for boys to girls in the student council election ? Express the raio in lowest terms.

1) 74:26 2) 37:13 3) 75:46 4)6:7
