A recipe uses 2.5 cups of flour to make 2 dozen cookies. If Pamela wants to make 72 cookies, how many cups of flour will she use

OpenStudy (destinymasha):

Proportions! 2.5/24 = x/72

OpenStudy (destinymasha):

72 divided by 24 is 3, do the same thing with the numerator -multiply 2.5 x3 = 7.5 So she would use 7.5 cups for 72 cookies
