Select one:

a. graham crackers

b. chocolate

c. marshmallows

Answer 1

Answer: b. chocolate

1/2 graham cracker, 1 marshmallow, and 4 squares of chocolate = ratio is 1/2 : 1 : 4

multiply with 2, we get ratio = 1 : 2 : 8

we have 9 whole graham crackers, 23 marshmallows, and 32 squares of chocolate = 9 : 23 : 32

divide by 9

9 / 9 : 23 / 9 : 32 / 9 = 1 : 2.56 : 3.56, but required ratio is ratio = 1 : 2 : 8, so chocolate is not fulfilled required number 8

Answer: b. chocolate ingredient will you run out of first.
