A recipe calls for 3 cups of flour for every 2 cups of sugar, if you need to make a batch that uses 10 cups of sugar, how many cups of flour will you need to use?
To solve this, set up a proportion: (3 cups flour / 2 cups sugar) = (x cups flour / 10 cups sugar). Cross-multiplying gives 2x = 30, so x = 15 cups of flour are needed.
=15
