20 Recipe Ratios

Sometimes you will have a recipe that is simply a ratio, or a set of ratios. For example, to make glaze you might use 1 milk, 8 parts powdered sugar. So how do you figure out how much of each to use if you want to make 6 cups of glaze?

First you set up an equation, like this:

1 part milk + 8 parts powdered sugar = 6 cups glaze

1 part + 8 parts = 9 parts

9 parts = 6 cups

Take those 6 cups and divide them into 9 parts: 6  LaTeX: \div  9 = LaTeX: \frac{2}{3}   

So that means that 1 part = LaTeX: \frac{2}{3}  cup

If 1 part =  LaTeX: \frac{2}{3}  cup, then 8 parts = LaTeX: 8\:\times\frac{2}{3}  cup, or LaTeX: 5\frac{1}{3}  cups

You would use LaTeX: \frac{2}{3}  cup milk and  LaTeX: 5\frac{1}{3}  cups powdered sugar to make 6 cups of glaze.

Lemonade can be made using 1 part sugar, 2 parts lemon juice, and 6 parts water. How much of each ingredient would you use to make 36 cups of lemonade?

1 part sugar + 2 parts lemon juice + 6 parts water = 36 cups lemonade

1 part + 2 parts + 6 parts = 36 cups

9 parts = 36 cups

36 LaTeX: \div  9 = 4

1 part = 4 cups

1 part sugar = 4 cups sugar

2 parts lemon juice = 2 LaTeX: \times 4 cups lemon juice = 8 cups lemon juice

6 parts water = 6 LaTeX: \times 4 cups water = 24 cups water
