Is a decimal an irrational or rational number?
A decimal can be both rational and irrational. Rational decimals are 0.25 , 0.234234234..., because they can be converted to a fraction. However, irrational decimals , such as pi = 3.141592.... cannot be converted to a equal fraction. A rational decimal are where the digits regularly repeat, and go to infinity, such as 0.234234234... However, irrational decimals, such as pi = 3.141592... were the digits go to infinity but there is no regular repetition of the numbers. Some other irrational decimals are the square roots of prime numbers. ;_ sqrt(2) = 1.414213562... sqrt(3) = 1.732050808... sqrt(5) = 2.236067978....
