It is asking you to find out how many cartons of orange juice and how many cartons of apple juice there will be in eight packs.
Let's practise
Small cartons of juices are sold in packs of five cartons.
A school buys eight packs for a trip.
How many cartons of each juice will there be?
orange juice
apple juice
- Read the question and then read it again. What is it asking you to do?
Show me
- Identify the ratio of part to part.
The language ‘for every’ will help you here.
Show me
The ratio is three cartons of orange juice for every two cartons of apple juice.
- How many packs of juices did the school buy for the trip?
Show me
Eight packs
- So, you must now multiply each of the parts by eight so the juices stay in the same ratio.
Show me
3 × 8 = 24 cartons of orange juice
2 × 8 = 16 cartons of apple juice
- What is your answer?
Check your working.
Show me
There are 24 cartons of orange juice and 16 cartons of apple juice.
You can use the total number of cartons to check the answer.
24 + 16 = 40 cartons in total
40 ÷ 8 = 5, which is the number of cartons in a pack.
