Gayle is making fruit punch that consists of 2 quarts of juice and 1 quart of soda water. How much soda water does she need if she has 5 quarts of juice?
2 quarts of juice ------- 1 quart of soda water 5 quart of juce ------- x quart of soda water ----------------------------------------------------------
x = 5*1/2 = 5/2 = 2,5
so she need for 5 quarts of juice 2,5 quart of soda water
