Unit 12 – Capacity and mass
1 We can use what we know about the relationship between
units of measurement to help solve problems. An egg cup has a capacity of 50 ml. A bottle has a capacity of 1 litre. How many of these egg cups can be filled with water from a full bottle? A soup recipe for two people uses 250 ml of water. The same recipe for eight people uses 4 times as much. How much water is needed for soup for 8 people? Carl pours 400 ml of milk from a full 2 litre container. How many millilitres of milk is left in the container? How much water is there in total? There are 2 litres and 500 millilitres more. We can write this as: 2 litres 500 millilitres (2 l 500 ml) 2 1 _ 2 litres 2.5 litres Explain why.
