An irrational number is a number that can be written as a decimal, but not a fraction. For example: 1.232323232323232....... any repeating decimal is an irrational number

Well, Zachary is right about it being a number that cannot be expressed as a fraction, but his example is not irrational - it is 122/99. In fact, ALL repeating decimals are rational. Numbers such as pi or square root of 2 are irrational.
