GCSE Ratio, Proportion & Rates Workbook

GCSE Ratio, Proportion & Rates Workbook is a five-mission GCSE Foundation activity book mapped to the DfE National Curriculum and Foundation assessment objectives for ratio, proportion and rates of change. Learners simplify and share in a ratio, express ratios as fractions and percentages, use the unitary method for direct and inverse proportion, scale recipes, map scales and currency, calculate percentage increase, decrease, change and reverse percentages, work out simple interest and compound growth, compare best buys, and use speed–distance–time and density–mass–volume formula triangles. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
