5. Question 5

   3 marks

   A jug holds 2 l 500 ml. A cup holds 250 ml. How many cups can be filled from the jug?

   (3 marks)

   Marking scheme

   Put both amounts in the same unit. The jug holds $2$ l $500$ ml $=2,500$ ml, and a cup holds $250$ ml. (1)

   Each cup takes $250$ ml out of the jug, so divide: $2,500÷250$. (1)

   $2,500÷250=10$. (1)

   Final answer: $10$ cups.

6. Question 6

   2 marks

   A recipe uses 400 ml of milk. How many millilitres are needed for 5 times the recipe?

   (2 marks)

   Marking scheme

   One recipe uses $400$ ml, so five times the recipe uses five times as much: $400\times 5$. (1)

   $400\times 5=2,000$ ml. (1)

   Final answer: $2,000$ ml, which is $2$ litres.

12. Question 12

    2 marks

    A bottle contains 1 l 200 ml of juice. How much juice is in 3 such bottles?

    (2 marks)

    Marking scheme

    First change the amount in one bottle to millilitres: $1$ l $200$ ml $=1,000+200=1,200$ ml. (1)

    Three bottles hold three times as much: $1,200\times 3=3,600$ ml. (1)

    Final answer: $3,600$ ml, which is $3$ l $600$ ml.

13. Question 13

    3 marks

    A petrol tank holds 45 l. If 18 l 500 ml is used, how much is left?

    (3 marks)

    Marking scheme

    Put both amounts in the same unit: $45$ l $=45,000$ ml, and $18$ l $500$ ml $=18,500$ ml. (1)

    What is left is the difference: $45,000-18,500$. (1)

    $45,000-18,500=26,500$ ml. (1)

    Final answer: $26,500$ ml, which is $26$ l $500$ ml.
