Check understanding

  • Compute (2/3) × (4/5) = 8/15 and show with an area model
  • Use a visual model to demonstrate (2/3) × 4 = 8/3 = 2 2/3
  • Simplify the product 3/4 × 2/3 = 6/12 = 1/2
“If a recipe uses 2/3 of a bag of flour and your child only wants to make 3/4 of the recipe, can they multiply those fractions to find out how much flour they need?”
