Question

What are rational numbers

Answer 1

A number is of the form $\frac{p}{q}$, where $p,q\ne 0\in Z$ is called rational numbers.
Example: (i) If $p=1$ and $q=2$ then $\frac{p}{q}=\frac{1}{2}$ is a rational number.
(ii) If $p=5$ and $q=1$ then $\frac{5}{1}=5$ is a rational number.
(iii) If $p=15$ and $q=10$ then $\frac{15}{10}=1.5$ is a rational number.
