Question

Which proportion correctly shows the equivalence of two ratios?

A. 2:3=27:18
B. 14:35=7:2
C. 4:5=32:40
D. 13:39=6:2

Answer 1

C. 4:5=32:40 is your answer

Treat each ratio like fractions. Note the equal sign. This means that, when each fraction is simplified, they would be the same.

4/5 = 4/5

(32/40)/(8/8) = 4/5

4/5 = 4/5

∴ (C) is your answer
