$\:\:$

Let us firstly understand what is rational number.

$\:\:$

$\underline{\bold{\texttt{Properties of rational numbers}}}$

$\:\:$

࿇ It can be expressed in the form of p/q where q $\rm \neq 0$

࿇ It's decimal expansion terminates at a point.

࿇ Numbers having non terminating repeating decimal expansion are also rational number.

$\:\:$

$\underline{\bold{\texttt{'0' in form of p/q}}}$

$\:\:$

• $\sf \implies \frac { 0 } { 1 }$

$\:\:$

• $\sf \implies \frac { 0 } { 2 }$

$\:\:$

In both the above examples 0 is written in the form of p/q where $\rm q \neq 0$

Hence '0' is a rational number
