Irrational Numbers, like irrational people, have no rhyme or reason. If you divide the numerator of a fraction by the denominator, the decimal portion is in most cases non-repeating and seemingly unpredictable. For example, pi, 3.1415..., the fraction 22 divided by 7. On the other hand, a rational number can be an integer, zero, or a fraction whose decimal portion leads to a finite end. For example, -1, 0, 1, 2, 3, the fraction 3 divided by 4, or 0.75.

Real numbers that are not rational?
√2 = 1.4142135.........π = 3.151912653.....Neither of these numbers can be written as a fraction of any kind, so cannot be a ratio, therefore are not rational. ■
Are rational numbers whole numbers?
The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.
