If the cocoa to water ratio for a hot chocolate recipe is 1 tablespoon cocoa to 1⁄4cup water, how much cocoa do you need if you use 1.5 cups of water?
1.5 cups of water is just 6 1/4 cups of water. So you will need 6 tablespoons of cocoa.
1. You set up a proportion to solve. If you divide 1 tablespoon of cocoa by 0.25 of water, the answer should be the same if you divide x cocoa by 1.5 cups of water.
So you set up the equation.
\(\frac{1}{\frac{1}{4}}=\frac{x}{\frac{3}{2}}\)
2. Then you solve by cross multiplying,
