Pi is an irrational number.
A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3.
There are fractions that are near Pi, for example:
22/7 = 3.142857 (PI = 3.14159265...)
A closer fraction is:
355/113 = 3.14159292
However whatever fraction you have, you will never get exactly PI. Hence it is irrational
