You need 20 oz. of punch with 3 parts ginger ale and 2 parts HI-C. So the end result will have 5 parts. To find out how many ounces are in each part, just divide the total (20) by the number of parts (5):
20 / 5 = 4
There will be 4 ounces per part.
First, solve for the amount of ginger ale. The problem says the punch is 3 parts ginger ale, so just multiply the number of parts by the amount in each part:
(3)(4) = 12
The punch will have 12 ounces of ginger ale.
Next, solve for the amount of HI-C. The problem says the punch is 2 parts HI-C, so just multiply the number of parts by the amount in each part:
(2)(4) = 8
The punch will have 8 ounces of HI-C.
Hope this helps!
