Question

A cookie factory uses 3/8 of a barrel of oatmeal in each batch of cookies with the factor uses 3/4 of a barrel of oatmeal yesterday how many batches of cookies did the factory make

Answer 1

(3/8) / 1 = (3/4) / x.....3/8 oatmeal to 1 batch = 3/4 oatmeal to x batches
cross multiply
(3/8)(x) = (3/4)(1)
3/8x = 3/4
x = (3/4) / (3/8)
x = 3/4 * 8/3
x = 24/12
x = 2 <==== 2 batches were made
