Question

Squash and water is mixed in the ratio 1:3 if 2 litres of drink is made, how much water is used?

Answer 1

If by 1:3 ratio, you mean that you have 4 total parts. Then 1.5 litres of water is used with 0.5 litres of squash to make 2 litres of drink.

Explanation:

1+3 = 4 parts of drink.

2L / 4 = 0.5 L

1 part squash = 0.5 L squash

3 parts water = 1.5 L water
