Rational Numbers

Sunday, October 18, 2009
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.
