Question

A batch of chicken required 4 6⁄7 cups of flour. If a fast food restaurant was making 3 3⁄4 batches, how much flour would they need?

Answer 1

Multiply 4 6/7 by 3 3/4:

34/7 times 15/4 comes out to

34     15        17(15)
---- * ---- = ---------------   (after reduction)
  7      4           7(2)

this comes out to 18.21 cups of flour total, to make 3 3/4 batches of chicken.
