You can put this solution on YOUR website! The ratio of Sarah's age to Aileen's age is 4:5 this year. Aileen was 12 years old 3 years ago. Find the ratio of Sarah"s age to Aileen's age in 9 years' time.
===============
Aileen was 12 years old 3 years ago --> Aileen is 15.
S:A = 4:5 = S:15
4:5 = S:15
5S = 60
S = 12 Sarah's age now.

In 9 yrs:
S = 21, A = 24
S:A = 21:24 = 7:8
