Ratio, Rate and ProportionCheatsheet

The whole topic on a page or two, for the night before.

A complete 24-page IGCSE guide to ratio, rate and proportion. It covers simplifying ratios, sharing in a ratio (with the bar model), unit rates, best-value comparisons, and speed, distance and time. A full section on kinematic graphs teaches how to read distance–time and velocity–time graphs, including gradient, acceleration and area under the graph. It then covers direct and inverse proportion, including y ∝ x², y ∝ √x and y ∝ 1/x². The guide finishes with percentages as proportion, and map scales with area and volume scale factors. Every method comes with step-by-step worked examples and clear diagrams. It ends with a summary, a keyword guide and exam tips.
