Question
3 litres of milk costs £12.00
Justin spent £36.00
How many litres of milk did he buy?
Solution
First, we need to find out the cost of one litre of milk. We know that 3 litres cost £12.00. So, to find the cost of one litre, we divide £12.00 by 3.
£12.00 ÷ 3 = £4.00
This means that one litre of milk costs £4.00.
Next, we need to find out how many litres of milk Justin bought. We know that he spent £36.00. So, to find out how many litres he bought, we divide £36.00 by the cost of one litre of milk (£4.00).
£36.00 ÷ £4.00 = 9
So, Justin bought 9 litres of milk.
