![]() ![]() ![]() non-terminating decimal numbers with infinitely repeating patternsĪny integer can be converted cleanly into a fraction, and is a rational number.įor example, 3 can be expressed as 3/1.There are four types of rational numbers: Though you learned what rational numbers are earlier in the article, it's helpful to break them up into broad categories, and look at different examples. And if a number can't be expressed this way, then it's an irrational number. So if a number can be expressed cleanly as a fraction, or a ratio between two integers, then it's a rational number. Some examples of rational numbers include:Īccording to Wikipedia, the term ratio "is derived from rational". ![]() Rational NumbersĪgain, a rational number is any number that can be expressed as a fraction, where both the numerator and denominator are integers, and the denominator is not 0: Source: Rational Numbers Integers are exactly like whole numbers, but can also include negative numbers. They do not include decimals or fractions, and since they start from 0 and go up, all whole numbers are positive. Note that whole numbers are just that – whole. Whole NumbersĪ whole number is any number from 0 up to infinity: 0, 1, 2, 3, 4, 5. What Are Whole Numbers and Integers?īefore getting into integers, it would be helpful to review what whole numbers are. In this article, we'll go over what whole numbers and integers are, cover different types of rational numbers, and learn how to determine if a number is rational or not. In other words, a rational number can be expressed as p/q, where p and q are both integers and q ≠ 0. A rational number is any number that can be written as a fraction, where both the numerator (the top number) and the denominator (the bottom number) are integers, and the denominator is not equal to zero. ![]()
