When baking cookies, the quantity of flour needed is a constant proportion of the number of cookies being made. If 24 cookies require 2 cups of flour, how many cups of flour will 60 cookies require?
G. 2 1/4
J. 4 1/2
The correct answer is K.
To solve this problem, set up a proportion showing the relationship between the quantity of flour and the number of cookies.
24 cookies is to 60 cookies as 2 cups of flour is to x cups of flour.
24/60 = 2/x
Solve for x
24x = 120
