Question 966920: 1000 ml of lemonade contains 250ml of lemon juice how much lemon juice does 750ml of lemonade contain? Answer by BC17(9) (Show Source):
Use this ratio to sub 750 mL of lemonade in
ie
Ratio 1 - 250 : 1000
Ratio 2 - x : 750
therefore 250 / 1000 = x / 750
* both sides of the equation by 750 so x is by itself
= 187.5 = x
Therefore 750 mL of lemonade must contain 187.5mL of lemon juice
