What’s inside:
Easy: simplifying two-part and three-part ratios, writing a ratio in the form 1:n, sharing an amount in a two-part ratio, and expressing a ratio as a fraction of the total.
Standard: sharing in three-part ratios, finding a total or a missing share from one known part, converting a ratio to a percentage, combining two linked ratios, unit-conversion ratios, map scales, and recipe and mixing problems using direct proportion.
Challenging: ratio-change problems where sweets or money are added or removed after sharing, combining ratios with a shared letter across three quantities, limiting-ingredient recipe problems, best-value comparisons, converting a fraction of a class into a ratio, and finding a total from a known difference between shares.

Every solution breaks the work down one step at a time, with the reasoning spelled out in plain English and every share, scale factor and unit conversion made explicit. Written for Foundation students who need clear, no-jargon, step-by-step method. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 10 and 11 students sitting Edexcel GCSE Foundation Mathematics (1MA1), plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
