The set of rational numbers
WebN = the set of natural numbers, Z = the set of integers, Q = the set of rational numbers, R = the set of real numbers. All these are infinite sets, because they all contain infinitely many … WebThe set of rational numbers is denoted as \(\mathbb{Q}\). Any decimal that terminates, or ends after a number of digits (such as 7.3 or −1.2684), can be written as a ratio of two integers, and thus is a rational number. We can use the place value of the last digit as the denominator when writing the decimal as a fraction.
