Solution

Verified by Toppr

A rational number is any number that can be written (expressed) as a fraction. For example, $2.5$ is a rational number because it can be expressed as $\frac{5}{2}$ .

Whereas, a whole number is a positive number without a fraction or decimal.

Therefore, the opposite is true. Every whole number is a rational number because it can be written as a fraction. $5$ can be written as $\frac{5}{1}$ . But, not all rational numbers are whole numbers.

Hence, every rational number is not a whole number.
