Question

Is zero a rational number? Can you write it in the form $\frac{p}{q}$, where $p$ and $q$ are integers and $q\ne 0?$

Answer 1

We know that, rational number is a number which can be written in the form of $\frac{p}{q}$, where $q$ is not equal to zero.

Thus, yes,

zero is a rational number, as it can be written in the form of

$\frac{p}{q}$.

Example : $\frac{0}{1}$, $\frac{0}{2}$, $\frac{0}{3}$, etc. where $0$ (zero) is an integer.
