How to tell if a number is rational or irrational?

Answer» If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number,then it is said to be rational and if it cannot be written in this form, then it is irrational.

Numbers that can be written in the form of a ratio or a fraction are called rational numbers. Irrational numbers cannot be represented as a fraction.
