Heather bought a jumbo bag of raisins with 27 cups of raisins in it. She wants to make oatmeal cookies, granola, and snack mix with the raisins. A batch of oatmeal cookies takes 3/4 of a cup of raisins. How many batches of oatmeal cookies can Heather make if she divides the bag of raisins equally among the cookies, granola, and snack mix?
Heather will have 27 / 3 = <<27/3=9>>9 cups of raisins for oatmeal cookies after dividing the bag.
Thus, she will be able to make (9/3) * 4 = <<9/3*4=12>>12 batches of oatmeal cookies.
