Fraction - GCSE Maths Definition

Reviewed by: Mark Curtis

Last updated

A fraction is a way of representing a part of a whole or a division of quantities. It consists of two numbers separated by a line, with the top number called the "numerator" and the bottom number called the "denominator". The numerator shows how many parts you have, while the denominator tells you how many equal parts the whole is divided into. For example, in the fraction ¾, the 3 is the numerator, and the 4 is the denominator, which means you have 3 out of 4 equal parts. Fractions are used in various calculations and concepts, such as comparing quantities, finding proportions, and solving problems in everyday contexts.
