Question

A cookie factory uses 2/3 of a barrel of oatmeal in each batch of cookies. The factory used 3 1/3 barrels of oatmeal yesterday. How many batches of cookies did the factory make?

Answer 1

3 1/3 = 10/3

10/3 divided by 2/3 = 10/3 times 3/2 = 5 batches of cookies

(10/3)/(2/3) = (10/3)(3/2)= 30/6 = 5
