# Is 10 rational or irrational?

A rational number is any number which can be expressed as a fraction $\frac{p}{q}$ where $p \mathmr{and} q$ are integers and $q$ is not equal to zero.
We can write that $10 = \frac{10}{1}$. In this fraction both numerator and denominator are natural numbers so $10$ is a rational number.
Any natural number (like $2 , 10 , 1978$ or other) or integer number (natural number or a number opposite to a natural one like $- 10 , - 3$ )can be expressed as a fraction with the number in numerator and $1$ in denominator. Hence they are all rational numbers.
