Rational number: Real numbers and topological properties, Overview & Terminology

In mathematics, a rational number is a number that can be expressed as the quotient or fraction ⁠ p q {\displaystyle {\tfrac {p}{q}}} ⁠ of two integers, a numerator p and a nonzero denominator q. For example, ⁠ 3 7 {\displaystyle {\tfrac {3}{7}}} ⁠ is a rational number, as is every integer (for example, − 5 = − 5 1 {\displaystyle -5={\tfrac {-5}{1}}} ).…
