Question

Use division to determine whether the ratios form a proportion.

12 : 44 and 3 : 11

A.
No. They do not form a proportion.

B.
Yes. They form a proportion.

Answer 1

12/44 = 3/11
.272727 = .272727
yup....thats a proportion

Answer 2

think about it...12/44 reduces to 3/11...and proportions are nothing but equivalent fractions

Answer 3

all ratios are proportions
anyway, check if 12/44 can be reduced
factors of 12 4*3
factors of 44 4*11
common factor 4 can be reduced
12/44 = 3/11 so yes B

Answer 4

Thanks :)
