      Ratio and Proportion

      Why this why now

      This unit builds from percentage change and because it utilises a formula it follows on from more work on algebra.

      Prior knowledge requirements

      • Convert between fractions, decimals, and percentages
      • Find percentages of amounts (including 50%, 25%, 10%)
      • Use percentage increase/decrease in context
