## Solution

As we know, a rational number is the one that can be written in the form of $$\frac{p}{q},$$ where $$q \neq 0$$
As we know, whole number is $$0,1,2,3,4,5 \ldots$$
Now, we know, every number can be written in the form of $$\frac{p}{q},$$ we get
$$\frac{0}{1}, \frac{1}{1}, \frac{2}{1}, \frac{3}{1}, \frac{4}{1}, \frac{5}{1}$$
Here, we can see that every whole number is a rational number.
But, every rational number $$\left(\frac{1}{2}, \frac{1}{3}, \frac{1}{4}, \frac{1}{5}, \frac{1}{6}\right)$$ is not a whole number as whole numbers are free from decimals and fraction.
Therefore, not every rational number is a whole number. But, every whole number is a rational number.
