Question

Write the rational number that is equal to its negative.

Answer 1

Determine the rational number that is equal to its negative.

A ration number which is equal to its negative zero

As for any integer $p,q\in \mathrm{\mathbb{Z}}$,$\frac{p}{q}=-\left(\frac{p}{q}\right)$ and if only if $\frac{p}{q}=0$

Hence, $“0”$ is the rational number that is equal to its negative.
