Question

Stefan has 4 1/2 cups of oats. He uses 3 1/4 cups to make granola bars for a camping trip. He saves the rest of the oats to feed to his parrot, Coco. If Coco needs 1/4 of a cup of oats each day, how many days can Stefan feed Coco with the oats he has left? Write your answer as a whole number, fraction, or mixed number. Simplify any fractions.

Answer 1

The initial amount of oats that Stefan had was 4 1/2 cups

He made granola bars with 3 1/4 cups.

Therefore, after that there was 4 1/2 - 3 1/4 = (4 - 3) (1/2 - 1/4) = 1 1/4 cups left.
