The rationals are characterized topologically as the unique countable metrizable space without isolated points. Please help improve this article by adding citations to reliable sources. Since the reals form an uncountable set, of which the rationals are a countable subset, the complementary set of irrationals is uncountable. The rational numbers, as a subspace of the real numbers, also carry a subspace topology. For example, for any two fractions such that. If both b and c are nonzero, the division rule is. Number of rational numbers can be found between two distinct rational numbers and b? Rational polynomial usually, and most correctly, means a polynomial with rational coefficients, also called a polynomial over the rationals.
