# Ratios question+ logical approach Watch

1. Thanks
2. It might not be the textbook answer but here's what I did:

Recipe = C : 2P : 4O : 6M : 12L
Have = 0 : 1.5 : 3 : 9 : 10

Mango juice is the one which exceeds its part in the recipe. If the recipe uses 1 litre of cranberry juice, not all of the mango juice will have been used, therefore the recipe needs to be scaled up to use up the mango juice. 9/6 = 1.5
So I will use 1.5 times the ratio of the juices in litres.

1.5L of cranberry juice , 3L of pineapple juice , 6L of orange juice , 9L of mango juice and 18L of lemonade

So compare this with the ingredients already in stock.
Things that need to be bought:
2 bottles of cranberry juice (1.5L needed, only sold in litres)
2 bottles of pineapple juice (3-1.5 = 1.5, only sold in litres)
3 bottles of orange juice (9-6 = 3)
8 bottles of lemonade (18-10 = 8)

2+2+3+8 = 15 bottles.
