Question

Is zero a rational number?

Answer 1

We know that, rational numbers are those numbers which can be expressed in the form $\frac{p}{q}$, where p and q are integers and $q\ne 0$
We know that $0$ divided by any number is equal to $0$.
So, $0$ can be expressed as $\frac{0}{5}$ or $\frac{0}{6}$

Hence, zero is a rational number.
