Does anyone know the answer to this?

Question

Sarah is following a cookie recipe that calls for 2 1/4 cups of butter. She has 13 1/2 cups of butter. How many batches of cookies can she make?

Answer 1

13 1/2 divided by 2 1/4

= 13.5/2.25

= 6 batches

or

(13 1/2)/(2 1/4)

= (27/2)/(9/4)

=(27/2)(4/9)

= (27/9)(4/2)

= 3(2) = 6
