A fraction describes how many parts of an object there are. You can use fractions to split a whole number into parts, such as halves or quarters.

Fractions can be written in words or as a figure. In maths sums, they are normally written as figures. For example, 'three-quarters' is represented as 3/4.

Numerators and denominators

Fractions are made up of two parts, the numerator and the denominator.

The numerator is the number above the line in a fraction and shows how many parts we have out of the whole. For example, in the fraction 1/4, the numerator is 1.

The denominator below the line shows how many equal parts there are in total and so what to divide the whole into.

For example, in the fraction ½, the denominator is 2.
