A recipe that makes 16 cookies calls for 1/4
cup of sugar and 2/3
cup of flour. Janelle wants to
proportionally increase these amounts to get a new recipe using one cup of sugar.
A. Using the new recipe, how much flour should she use?
B. How many cookies can she make with the new recipe?



Answer :

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
