Question

Will has 15 cups of flour. He wants to make 3 batches of cookies; each batch used 2 3/5 cups of flour. Does he have enough flour to make three batches?

Answer 1

Yes

Explanation:

first you make 2 and 3/5 into an improper fraction, which is 13/5. Then you multiply this by 3, for the 3 batches, giving you 39/5. 15 times 5 is 75, so he has 75/5 cups of flour, and he only needs 39/5. Yes he has enough flour.
