Is zero a rational number?

Yes zero is a rational number.

We know that the integer 0 can be written in any one of the following forms.

For example, 0/1, 0/-1, 0/2, 0/-2,  and so on …..
In other words, 0 = 0/q, where q is any non-zero integer

Thus, 0 can be written as, where p/q = 0, where p = 0 and q is any non-zero integer.

Hence, 0 is a rational number.
