Question

which of the following are rational numbers -3, -2/3, 4/0, 0/-5

Answer 1

The rational numbers are -3, -2/3,0/-5..

➡️Why the rest(4/0) aren't rational?

Bcz if a number should be a rational number, it should be able to written in the form p/q where p& q are integers are q NOT equal to 0.

So in 4/0, q is 0. So not rational..

Moreover it's not a number at all...bcz it is of indefinite form

Answer 2

-3, -2/3, and 0/-5 are rational numbers because they are in p/q form where q not equal to 0. But 4/0 is not a rational number as q cannot be 0 but here q is 0.
