Answer 1

The correct option is A rational number

A number which can be expressed as $\frac{p}{q}$, where p and q are integers and $q\ne 0$, is known as rational number.

Examples:

1. $\frac{-2}{3}$ is a rational number since -2 and 3 are integers and 3 ≠ 0.
2. 7 is a rational number since 7 can be written as $\frac{7}{1}$, where 7 and 1 are integers and 1 ≠ 0.
3. $\frac{0}{100}$ is a rational number since 0 and 100 are integers and 100 ≠ 0.
