Best Answer

A rational number is a number that can be expressed as a fraction. For example, the number 5 is a rational number because as a fraction it is 5/1. The number 0.5 is a rational number because as a fraction it is 1/2. The square root of 3 is not a rational number, as it can not be expressed as a simple fraction.
