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

0.75 when represented as rational number, is

0.4bar27 represents the rational number

0.4bar27 represents the rational number

0.4bar27 represents the rational number

0.4bar27 represents the rational number

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)

Can we represent all rational numbers pictorially ?

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 int_(0)^((pi)/(3))cos^(4)xdx=a pi+b sqrt(3) ,where "a" and "b" are rational numbers,then "9a+8b" is equal to:
