Question

Is 10 rational or irrational?

Answer 1

It is a rational number.

Explanation:

A rational number is any number which can be expressed as a fraction `p/q` where `p and q` are integers and `q` is not equal to zero.

We can write that `10=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.
