Question

Sam spends exactly £40 on petrol.

The petrol costs £1.75 per litre.
Work out the number of litres of petrol she buys.
Give your answer to 1 decimal place.

Answer 1

You don't need to overthink this one, it's not asking for any exact values or estimates so all you do is 40/1.75 which gives you 22.8571428571. Since it's asking for 1 decimal place then the answer would be 22.9 litres of petrol.

Answer 2

Answer: 22.9

Explanation:

1. 40 divided by 1.75 = 22.8571428571

2. Round that up to 22.9
