anonymous · Answer

This is easy

Rational numbers are those numbers which can be expressed in the form p/q, where p and q are integers and q is not zero.

eg : 2/3 , 5/12 etc.  They have either terminating decimal expansion or non-terminating but repeating decimal expansion

On the other hand irrational number are those which cannot be expressed in the form p/q

eg : root2, root5 etc.

Irrational numbers have a non-terminating and non-repeating decimal expansion
