Question

the present age of father is 45 years and her daughter is 20 years find the ratio of age of father to the age of father when daughter was 15 years old​

Answer 1

Answer:

8:3

Step-by-step explanation:

If the daughter is 20 years old today, then she was 15 years old  (20-15=5) years ago.

so, five years ago the daughter was 15 years old while the father was (45-5=40) years old.

The ratio of the age of the father to that of his daughter 5 years ago is;

$\frac{40}{15}=\frac{8}{3}$

Which can be expressed as 8:3

Therefore, the ratio of age of father to the age of father when daughter was 15 years old​ is 8:3
