Fractions

Bayani Gaba-gaba

Fractions express parts of a whole and sit at the heart of almost every topic in the Edexcel IGCSE specification, from ratio and proportion through to algebraic manipulation and probability. Confident fraction work on Paper 1 (non-calculator) is often the difference between losing and gaining marks.

You will learn to simplify, order, convert and calculate with fractions and mixed numbers, building fluency that transfers directly to algebra where the same rules apply with letters instead of digits.

Takardar Darasi

Sharing a pizza equally among friends, reading a measuring jug, mixing paint in a given ratio: fractions describe portions of a quantity. Every fraction has a numerator (top) telling you how many parts you have, and a denominator (bottom) telling you how many equal parts the whole is divided into.
