Question

A recipe calls for 2 1/2 cups of flour to make 24 cookies how many cups of flour would be required to bake 15 dozen cookies

Answer 1

15 dozen = 180 cookies

180 ÷ 24 = 7.5

7.5 x 2.5 = 18 3/4 cups of flour

Answer 2

let 'X' represent the cups of flour required to make 15 dozen cookies.

15: X=2 : (5/2) (since 2 1/2=5/2)

x=75/4

×=18 3/4 cups

18 3/4 cups are required to bake 15 dozen of cookies.
