What is the difference between a rational number and an irrational number?

Rational numbers can be written as a fraction. They include natural numbers, whole numbers, integers, fractions, repeating decimals, and terminating decimals. Irrational numbers cannot be written as a fraction. They include decimals that never repeat and never terminate. Both rational and irrational (non-terminating) numbers are real numbers.
