Question

Which of the following are rational numbers and which are not?

$\frac{-3}{4}$

Answer 1

A rational number is defined as a number that can be expressed in the form $\frac{\mathrm{p}}{\mathrm{q}}$ where $\mathrm{p}$ (numerator) and $\mathrm{q}$ (denominator) are integers $(\mathrm{q}\ne 0)$.

Here, in $\frac{-3}{4}$, $\mathrm{p}=-3$ and $\mathrm{q}=4$.

Hence, $\frac{-3}{4}$ is a Rational Number.
