Well an an irrational number is a real number that cannot be expressed as a ratio of integers, i.e. as a fraction. A rational number is a number that can be written as a ratio. So 3/7 is a rational number, 0.38(with a line saying its continuous over .38) is rational, Square of 7/9 is irrational number, and 5 pi is an irrational number.
