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.
