Ratio Problems

Mathematics · Ratio & Proportion · procedural

Solve problems involving the relative sizes of two quantities where missing values can be found by using integer multiplication and division facts

What mastery looks like

  • If the ratio of red to blue beads is 3:5 and there are 15 blue beads, find the number of red beads
  • Use multiplication facts to find the missing value: 'For every 2 apples there are 5 oranges; if there are 20 oranges, how many apples?'
  • Explain the multiplicative relationship between two quantities in a ratio context

Check your understanding

If a recipe uses 3 eggs for every 200g of flour, can Ratio Problems work out how many eggs would be needed for 600g of flour?
