A fruit punch is made by mixing pineapple juice, orange juice, and lemonade in the ratio 1 : 3 : 6.

Question

If 500 ml of pineapple juice is used, how much orange juice is needed?

Answer 1

The total ratio of the mixture is 1 + 3 + 6 = 10.
If 500 ml of pineapple juice is 1 part of the mixture, then:
3 parts of the mixture would require 3/1 x 500 ml = 1500 ml of orange juice.
Therefore, 1500 ml of orange juice is needed.
