Rational Numbers Can be expressed as a ratio of two Integers: a/b, (b ? 0); such ratios (fractions) can be expressed as terminating or repeating decimals
An irrational number cannot be written as the ratio of two integers • The square root of any whole number that is not a perfect square is irrational The cube root of
