Rational number

Closure property

assume two rational numbers say x and y. the results  of addition and multiplication operations give a rational number we can say that rational number are closed under addition and multiplication . For example

rational number are not closed under division as  1 and 0 are rational number  but 1/0 is not defined but it is closed under addition  and multiplication

that is 1+0 = 1 closed under addition

          1*0 =0 closed under multiplication

but 1/0  is not defined so it is not closed under division

Hence Rational numbers are closed under addition ,multiplication but not closed under division
