# Is -8 a rational number?

• Last Updated : 23 Feb, 2022

Rational numbers are of the form p/q, where p and q are integers and q ≠ 0. Because of the underlying structure of numbers, p/q form, most individuals find it difficult to distinguish between fractions and rational numbers.

It includes all the integers and can be expressed in terms of fractions or decimals. It is denoted by ‘Q’.

Examples: -8 , -5 ,-69 etc …..

### Is -8 a rational number?

A rational number is a sort of real number that has the form p/q where q≠0. When a rational number is split, the result is a decimal number, which can be either a terminating or a recurring decimal.

Here, the given number, -8 can be expressed  in the form of p/q, -8/1 and we can write -8  as -8/1 and -8 is also a negative integer .

Hence, -8 is a rational number.
