A rational number is defined as a number which can be expressed as a fraction , where and fraction in its lowest terms. ... X is an irrational number if it cannot be written as the ratio of two different integers. 2 can be written as 2/1, as there is a 1 under every integers. So 2 is not an irrational number.
