Question

Two numbers are in the ratio 4:5. Their highest common factor is 16. What is a pair of numbers that fits that?

Answer 1

The numbers are `64` and `80`.

Explanation:

The two numbers are in the ratio `4:5` and there is no common factor between `4` and `5` (i.e. highest common factor is `1`).

As the highest common factor of the two numbers is `16`,

the numbers are `4xx16` and `5xx16` i.e. `64` and `80`.
