Understanding fractions

Mathematics · Multiplication & Division · procedural

Solve problems involving scaling by simple fractions and problems involving simple rates

What mastery looks like

  • A recipe for 4 people needs 200 g of flour — how much for 6 people?
  • If 3 kg costs £12, how much does 5 kg cost?
  • Scale a shape by a factor of 1/2 and find the new dimensions

Check your understanding

If a recipe serves 4 and Understanding fractions wants to make it for 6, can they scale up each ingredient — for example, changing '2 cups of flour' to '3 cups'?
