A rational number is one that can be expressed as a ratio or a fraction: 1:5, 2/7, 23/77. An irrational number cannot. If you can write it as a decimal which ends or repeats, it is rational. Typical irrational numbers are things like pi (3.1415926535...), e (2.71828...), and most square roots (root 2 = 1.4142...).
