okay, so for every 2 litres of water, you want 100 ml of juice. So if you were only using 1 litre, you would also half the amount of juice, for 50ml, i.e. you want to use 50ml of juice per litre of water. So how much juice would you use for 5 litres, and then what's the total amount of drink?

2 litres of water = 1 drink
4 litres of water = 2 drinks
6 litres of water = 3 drinks

do you see the trend? if so, then where do you think 5 litres of water will lie on that list and how many drinks do you think that will be?
