Description
This casefile breaks down three of the most important (and most misused) areas of school maths: percentages, ratio, and proportion — the stuff that shows up everywhere in exams and real life.
Instead of throwing formulas at you, this book focuses on what you actually need to be able to do: increase and decrease amounts by a percentage, work backwards to find the original value, compare quantities using ratio, and solve proportional problems with confidence.
Each section is structured like an investigation. Concepts are introduced clearly, worked through step by step, and reinforced with examples that show why each method works — not just how to copy it. There’s no filler, no gimmicks, and no assumption that you already “get it”.
This is a printed casefile designed to be written on, annotated, and kept as a reference — ideal for revision, exam prep, or fixing gaps that have quietly built up over time.
Whether you’re a student who keeps losing marks on percentage questions, a parent trying to help without re-learning everything, or a teacher wanting a clear, no-nonsense resource — this casefile gives you the tools to stop guessing and start solving.
