Situation 1: Recipe for tropical punch
Number of cups of pineapple juice = 2.
Number of cups of orange juice = 3.
Total number of cub of juice = 2+3 = 5 cups.
Let us find % of pineapple and orange juice in total number of cups of juice.
% of pineapple = 2/5 = 0.40 = 40%.
% of orange juice = 3/5 = 0.60 = 60%.
Situation 2: Jo's drink
Number of cups of pineapple juice = 3.
Number of cups of orange juice = 4.
Total number of cub of juice = 3+4 = 7 cups.
Let us find % of pineapple and orange juice in total number of cups of juice.
% of pineapple = 3/7 = 0.429 = 42.9%.
% of orange juice = 4/7 = 0.0.571 = 57.1%.
Please note: In Jo's drink pineapple juice % increased and orange juice % decreased by the tropical punch recipe.
