Question

Define rational numbers.

Answer 1

A rational number can be defined as any number which can be written in the form of $\frac{p}{q}$where $pandq$are integers and$q\ne 0$ is a rational number.

Example:

Let$\frac{-3}{4}$ be a number.

Here $\frac{-3}{4}$is written in the form $\frac{p}{q}$ where$pandq$ are integers such that $p=-3andq=4\ne 0$

Thus,

$\frac{-3}{4}$ is a rational number.
