Question

The sum of a whole number A and a whole number B is 20, and the ratio A : B is equivalent to 2 : 3. Find A and B.

Answer 1

Answer: A=8 and B=12

Explanation:

If A+B = 20 and ratio A:B is 2:3, add both sides of the ratio to get 2+3=5

Multiply the ratio by the total divided by the added sides to get 8:12

Or just do:

2:3 =5

4:6 =10

6:9 = 15

8:12 = 20
