A rational is a number that can be expressed as the ratio of two integers.

ℚ

In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, p and q, with the denominator q not equal to zero. Since q may be equal to 1, every integer is a rational number. The set of all rational numbers is usually denoted by a boldface Q (or blackboard bold (\mathbb{Q} in LaTeX), Unicode ℚ); it was thus denoted in 1895 by Peano after quoziente, Italian for "quotient".
