To make a batch of 36 cookies, Denis needs 1 1/2 cups of flour, 2 3/4 cup of sugar, and 1/8 cup of milk. Calculate the amount of each ingredient that Denis need to make 12 dozen cookies
A dozen is 12; thus 12 dozen is 12*12 = 144.
144/36 = 4
Therefore Denis is making 4 times as many cookies; meaning he needs 4 times the ingredients.
(1 1/2) * 4 = 6 cups of flour
(2 3/4) * 4 = 11 cups of sugar
(1/8) * 4 = 1/2 cup of milk
Thus Denis needs 6 cups of flour, 11 cups of sugar, and 1/2 cup of milk to make 12 dozen cookies.
