A rational number is a number that can be represented as a fraction (or ratio).
Whole numbers are rational numbers in disguise, since there is no obvious fraction.
Whole numbers can indeed be represented as a fraction, and are therefore rational numbers. There is always a "diguise" with the whole number in the numeratore and an implied "1" in the denominator.
