Answer 1

The answer is 8.

Ratio is a relationship among two numbers representing how many times the first number contains the second. The tip with ratios is to constantly multiply or divide the numbers by the same value.

When you multiply each number by four the sum will be 28.

2 x 4 = 8

5 x 4 = 20

The total is 28.
