For field day, Mrs. White is preparing punch. She wants to make 6 gallons of punch. The
recipe she found is only for 3 quarts. The recipe calls for 1 1/5 cups of pineapple juice, 1/2
cup of orange juice, and the rest lemon-lime soda. In order to make 6 gallons of punch,
how much of each ingredient will Mrs. White need?
Conversion formula
1 Gallon = 4 Quarts
= 16 Cups
=> 1 Quarts = 4 Cups
------------------------------------------------------------------------
Mrs. White has recipe for 3 quarts (12 cups)
1 1/5 cups of pineapple juice
(6/5 cups)
1/2 cup of orange juice
and Rest (12 - 6/5 - 1/2 = 103/10 cups)
of lemon lime soda
these are the recipes for 3 Quarts
(12 cups) of Punch
------------------------------------------------------------------------
We want the recipe for 6 gallons
of punch
=> 6 gallons = 6 * 16 = 96 cups
but 96 = 12 * 8
each recipe for 12 cups gets
multiplied by 8
required recipe for 6 gallons of
punch is
6/5 * 8 = 48/5 = 9 3/5 cups of pineapple juice
1/2 * 8 = 4 cups of orange juice
f 13/10 * 8 = 412/5 = 82 2/5 cups of lemon-lime soda
