If A & B are two rational numbers and AB, A + B and A -B are rational numbers, then A/B is :

If A&B are two ratinal numbers and AB,A+B and A-B are rational numbers, then A/B is: a.always rational b.never rational c.rational when B!=0 d.rational when A!=0

If A and B are two rational number and AB, (A+B) and (A-B) are rational numbers, then (A/B) is (where B ne 0)

If A and B represent a rational number,then (A-B) is equal to

If a/b and c/d be two rational numbers and if a = nc, b = nd,when n is a natural number , then what type of rational numbers are the numbers a/b and c/d and why ?

If in DeltaABC, A =90^(@) and c, sin B and cos B are rational number, then

If in DeltaABC, A =90^(@) and c, sin B and cos B are rational number, then

If in DeltaABC, A =90^(@) and c, sin B and cos B are rational number, then

If a and b are any two rational numbers then a rational number between a and b is
