The term "Rational Numbers" refers to the fact that a rational number represents a ratio of two integers. Rational Numbers are numbers that can be expressed exactly by a ratio of two integers. Or more simply put, a rational number is an integer that can be expressed as a simple fraction. An example of a rational number is

**5** because 5 can also be expressed as 5/1, or

**4 **because 4 can be expressed as 16/4.

An irrational number is a number that cannot be written as a simple fraction and has a decimal that goes on forever without a pattern. An example of an irrational number is Pi - 3.14159265... etc.
