Question

to make 3 dozen cookies, 1 1/4 cups of pecan halves are required. how many dozen cookies can be made with 5 cups of pecan halves?

Answer 1

12 dozen

Explanation:

create a proportion of: dozen cookies / cups of pecan

let 'd' = dozen cookies

(3/1 ÷ 5/4) = (d ÷ 5)

simplify 3/1 ÷ 5/4 to be: 3/1 x 4/5, which equals 12/5

12/5 = d/5

cross-multiply to get:

5d = 60

d = 12
