Why Is Zero A Rational Number?

I've been studying about the real number system this weekend, and there's
something I don't quite understand.

My notes define a rational number as a number which can be written as a ratio
of two integers, where the denominator is not zero.

So, if the denominator cannot be zero, (because division by zero is impossible
and undefined, correct?), then how can zero be written as a ratio of two

Any insight on this will be appreciated. Thanks.
