You make punch for a party. the ratio og ginger ale to fruit juice is 8 cups to 3 cups. you decide to add 4 more cups of ginger ale. how many more cupsof fruit juice do you need to keep the correct ratio.

To get the answer we can use proportion
8 ginger ----------------- 3 fruit
12 ginger ----------------x
Crossmultiply now
8x=12*3                /:8
x=
x=
To not change ratio we have to have 4.5 cups of fruilt juice. We initialy had 3, so we have to add 1.5 cup of fruit juice.
