Rational numbers are those numbers that can be expressed as a quotient (the result in a division equation) or in the format of a simple fraction. Zero is not a rational number.

As shown in the table below, a rational number is one that takes the form of a numerator (p) divided by (/) a denominator (q) when both are regular integers and q does not represent zero.
