  3. True · The empty scale should show zero before fruit is placed on it.
  4. Read the jug at eye level · Read the measuring jug's marks at eye level.
  5. litres · Litres are convenient for the volume a large tank can hold. Empty describes its current contents.

  7. 1 · 1000 ml is exactly 1 litre.
  8. How much water is in the jug? · The amount of water in the jug is a liquid volume.
