# Rational number

A **rational number** is any number that can be expressed as the quotient or fraction of two integers, a numerator p and a non-zero denominator q.^{[1]}

## ExamplesEdit

- 5
- 0.2

Notice the number 5 in second example! It is because all numbers are divisible by 1 and at such it is actually but it is more convenient to write it as 5.
**Note** Though all numbers are divisible by 1 some numbers are considered irrational ie they cannot be represented in the form also **note** that it impossible to have a number with 0 as the denominator (b must not be equal to 0 in ).
