Mrs. Neville is baking 5 batches of cookies. She will need 2 1/3 cups of flour for each batch of cookies. If she begins with a bag of flour that contains 20 cups, how many cups
of flour will be left in the bag? (Show work on your paper)

8.33 cups of flour

Step-by-step explanation:

In order to find the answer to this question you need to multiply the amount of batches by the amount of flour it takes to make that batch and then just simply make sure the answer is a mixed number.

Convert the mixed number into a improper fraction:

Remember that all whole numbers have a invisible denominator:

Now subtract from 20 cups:

Find the common denominator

CD = 3

20 1 - 35 3 = (20 × 3) + (35 × 1) 1 × 3 = 60 - 35 3 = 25 3 = 8.33

Hope this helps.
