Question

Choose the statement that correctly lists equivalent ratios.

A. 1 : 6 = 20 : 120 = 5 : 30
B. 1 : 6 = 4 : 18 = 6 : 36
C. 1 : 8 = 20 : 120 = 3 : 24
D. 1 : 8 = 3 : 32 = 5 : 48

Answer 1

C

Answer 2

Which ratio is equal to 3 : 5?
A. 12 : 25
B. 12 : 20
C. 15 : 20
D. 12 : 15

Answer 3

you want to find out which answer reduces to 3:5, so its best to think of them as fractions. for example:\[12:20\rightarrow \frac{12}{20}=\frac{\not4\cdot3}{\not4\cdot5}=\frac{3}{5}\rightarrow 3:5\] so your answer is 12: 20. Just think of reducing fractions. Likewise, you will see that the answer to your first question is really A.
