Question

A recipe that makes 16 cookies calls for 14 cup of sugar and 23 cup of flour. Janelle wants to proportionally increase these amounts to get a new recipe using one cup of sugar.

1. Using the new recipe, how much flour should she use? Explain or show your work.

16 cookies ¼ cup of sugar ⅔ cups of flour

??? 1 cup of sugar 2 ⅔ cups of flour

Answer 1

64 cookies : 1 cup of sugar : 8/3 or 2 2/3 cup of flour

Explanation:

16 cookies : 1/4 cup of sugar : 2/3 cup of flour

Multiply each part by 4 to find how much flour and how many cookies would be used in the same recipe with 1 cup of sugar.

64 cookies : 1 cup of sugar : 8/3 or 2 2/3 cup of flour
