​

Answer 1

Answer:

d all of these. I think it will help you

Answer 2

Answer:

c) A*b will also be a rational number

because if we do a + b then we have to take LCM and if it take LCM then the number will not be a relational number if we do a minus the then again we have to take LCM and if we again take LCM then the number will not be a rational number therefore the one and only option C which is a need to be will be our rational number because in multiplication of rational number we have to do the multiplier of above number with above and below number with below therefore into being will be the rational number
