Question

Check whether the following is not a rational number:​
(i) $-3$.

Answer 1

We know that,

If $p$ and $q$ is an integer and $q\ne 0$, then the number of the form $\frac{p}{q}$ is called a rational number .

Given, number is $-3$

And $-3$ can be written as $\frac{-3}{1}$.

Where, the numerator is $-3$ and denominator is $1$.

which are integers and denominator is not $0$.

Hence, $-3$ is a rational number.
