Question

What is the value of "a" if the number (-11/a ) is not a rational number?
​

Answer 1

Answer:

Here if the value of a is equals to zero then 11/a will not be a rational number.. rational numbers are the numbers which can be written in the form of p/q where q should not be equal to zero because any number divided by zero will become not defined and hence we cannot define that number as rational number ... ..
