Explanation:

1- Rational numbers:

Rational number is any number that can be written in the form of a fraction where both a and b are integers and b ≠ 0.

2- Natural numbers:

Natural number is a counting number (1,2,3,4,.....etc)

Now, we know that any number if divided by 1, the result would still be the same number ()

This means that if any natural number is divided by 1, the result would still be the same natural number.

We can now conclude that natural numbers can be written in the form of fraction with denominator equal to 1.

This means that a natural number can always be a rational number.
