Percentages
Bayani Gaba-gaba
Percentages appear everywhere: exam scores, shop discounts, bank interest rates, population growth and tax calculations. Mastering them gives you a single, flexible tool for comparing proportions, measuring change and solving financial problems across the entire Edexcel IGCSE specification.
This topic builds from the basic idea that 'per cent' means 'per hundred', through conversions and calculations, all the way to reverse percentages and compound interest. You will see how the multiplier method turns multi-step percentage problems into a single multiplication, saving time and reducing errors on both calculator and non-calculator papers.
