Is zero a rational number? Can you write it in the form $\frac{p}{q}$,where $p$ and $q$ are integers and $q \ne 0$?

(A) Yes,zero is a rational number. $A$ rational number is defined as any number that can be expressed in the form $\frac{p}{q}$,where $p$ and $q$ are integers and $q \ne 0$. Since zero can be written as $\frac{0}{1}$,$\frac{0}{2}$,$\frac{0}{3}$,etc.,where the numerator $p = 0$ (an integer) and the denominator $q$ is any non-zero integer,it satisfies the definition of a rational number.
