Quick Answer. Q represents rational numbers because all rational numbers are a quotient. This means that each rational number can be expressed by a fraction with a denominator other than zero and a numerator that is a whole number. Whole numbers, fractions and decimals are all rational numbers.
Cardinal number. In mathematics, cardinal numbers, or cardinals for short, are a generalization of the natural numbers used to measure the cardinality (size) of sets. The cardinality of a finite set is a natural number: the number of elements in the set. The transfinite cardinal numbers describe the sizes of infinite sets.
