Answer:
Here we may have that all the numbers are tripled, so we have that:
the recipe needs:
2 cups of pineapple juice.
3 cups of orange juice.
Then the ratio of pineapple juice to orange juice is 2 to 3, then out of 5 total cups, 2/5 = 0.4 of the drink is pineapple, and 3/5 = 0.6 is orange.
Jo creates a drink that uses 3 cups of pineapple juice and 4 cups of orange juice.
In Jo drink we have that the ratio is 3 to 4, this means that the ratios are different, out of 7 total cups we have that 3/7 = 0.43 is pineapple and 4/7 = 0.57 is orange.
So in Jo's drink, the proportion of orange is smaller and the proportion of pineapple is bigger.
