(discrete mathematics) if m and n are nonzero integers, show that (2m+3n)/5mn is a rational number.

is a rational number for any m and n; nonzero integers.

Step-by-step explanation:

We have been given that 'm' and 'n' are nonzero integers. We are asked to show that is a rational number.

We can rewrite our given number as:

Cancelling out common terms:

Since 'm' and 'n' are nonzero integers, so each part will be a rational number.

We know that sum of two rational numbers is always rational, therefore, our given number is a rational number.
