Question

The ages of Laura and Bella are in the ratio 4:5. Three years ago, the ratio of their ages was 7:9. Find their present ages.

Answer 1

Step-by-step explanation:

The ratio of the ages of Laura and Bella = 4x:5x

4x-3/5x-3 = 7/9

9(4x-3) = 7(5x-3)

36x-27 = 35x-21

x = 6

The present ages of Laura and Bella are 24 & 30
