Read the first 6 Ratio and Proportion (Foundation Maths) flashcards as text

  1. Simplify the ratio 18 : 24 to its simplest form.

    Answer: 3 : 4

    The highest common factor of 18 and 24 is 6, so dividing both parts by 6 gives 3 : 4.

  2. Share £150 between Amy and Ben in the ratio 2 : 3. How much does Ben get?

    Answer: £90

    There are 2 + 3 = 5 parts, so one part is £150 ÷ 5 = £30. Ben gets 3 parts = £90.

  3. A recipe for 4 people uses 300 g of flour. How much flour is needed for 10 people?

    Answer: 750 g

    For 1 person, 300 ÷ 4 = 75 g. For 10 people, 75 × 10 = 750 g.

  4. Write the ratio 2 : 5 in the form 1 : n.

    Answer: 1 : 2.5

    Divide both parts by 2: 2 ÷ 2 = 1 and 5 ÷ 2 = 2.5, giving 1 : 2.5.

  5. The exchange rate is £1 = €1.15. How many euros would you get for £240?

    Answer: €276.00

    Multiply the pounds by the rate: 240 × 1.15 = €276.

  6. In a class, the ratio of boys to girls is 3 : 4. There are 12 boys. How many students are in the class altogether?

    Answer: 28

    3 parts = 12 boys, so 1 part = 4. Girls = 4 × 4 = 16. Total = 12 + 16 = 28.
