Rational Numbers. Rational Numbers, class of numbers that are the result of dividing one integer by another. Integers are the negative and positive whole numbers (... -3, -2, -1, 0, 1, 2, 3, ...). The numbers ? , 5 (5/1), and -1.4 (-7/5) are therefore rational numbers because they are quotients (results of division) of two integers. Rational numbers are a subset of the real numbers, which also include the set of irrational numbers. Irrational numbers are numbers such as pi (p), the square root of two (Ã ), and the mathematical constant e that are not the quotient of any two integers. All rational numbers can be written as decimal numbers. The decimals may have a definite termination point (such as 5 or 3.427) or they may endlessly repeat in a pattern (such as 1.8888... or 2.18181...).
