He proved that the square root of 2 cannot be written in the fraction form, so it is irrational. On the A whole number is an integer, and as such is rational: Another obvious way of determining rationality is if a number is a ratio itself. A rational number includes any whole number, fraction, or decimal that ends or repeats. Rational numbers are those numbers that are integers and can be expressed in the form of x/y where both numerator and denominator are integers whereas irrational numbers are those numbers which cannot be expressed in a fraction. Irrational numbers include surds and special numbers such as . What is rational and irrational number with example?
