Question

A water tank is 5/8 full. It needs 330 Litres to fill it. What will the tank hold when full? ​

Answer 1

528 Litres

Explanation:

If 5/8 is 330 Litres

you want to work out what 8/8 is

the first step you would take is to find 1/8. you can do this by dividing by 5

therefore 1/8 is 66 Litres (what you do to one side, you must do to the other)

now, you are able to find 8/8. you do this by multiplying both sides by 8

therefore you get 8/8 or 1 whole is 528 Litres
