Those numbers which can be written in the form are called Rational Numbers.

Since is of the form  , that's why it is a rational number. Also the decimal 

representation of is non-terminating but repeating (because after decimal the number 

142857 will repeat every time). So, is a rational number.

 

But is not rational because because is not exactly equal to . So, is irrational.
