It's possible to say that zero is rational because it's a whole number and rational number is a fraction or a whole number.
Right?

A rational number is a number that can be expressed as a fraction, p/q, where p and q are integers and q is non-zero.

Not necessarily, as (-6)/(-2) = 3, which is a whole number. Note that some people use the term "whole number" to mean a non-negative integer, and that a rational number can be negative.

$0=\frac0r$, where $r$ is any real number other than $0$.
