Fraction

fraction is a real number written as a quotient, or ratio, of two integers \(a\) and \(b\), where \(b\neq 0\).

\[\dfrac{a}{b}\]

The integer above the fraction bar \(a\) is called the numerator and the integer below \(b\) is called the denominator.

The numerator is often called the “part” and the denominator is often called the “whole”. Equivalent fractions are two equal ratios expressed using different numerators and denominators.
