Give an example to support the statement "the aum of two rational numbers is always rational​

Answer»

ANSWER:

A RATIONAL NUMBER is a number which can be EXPRESSED as the ratio (QUOTIENT) of two integers. Let M and N be any two rational numbers and let S = M+N. Then there exists integers a, b, c and d such that M = a/b and N = c/d. So S = (ad+bc)/bd.
