Stefan has 4 1/2 cups of oats. He uses 3 ¼ 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?
4(4 1/2 - 3 1/4) = 5
To find out how many days Stefan can feed Coco with the oats he has left, we need to subtract the amount he used for making granola bars from the total amount of oats.
4 1/2 cups - 3 1/4 cups = 9/2 cups - 13/4 cups (To subtract fractions, we need a common denominator, which in this case is 4)
9/2 cups - 13/4 cups = 18/4 cups - 13/4 cups = 5/4 cups
So, Stefan has 5/4 cups of oats left.
Now, we need to calculate how many times 1/4 cup fits into 5/4 cups.
(5/4 cups) ÷ (1/4 cups) = 5/4 * 4/1 = 20/4 = 5
Therefore, Stefan can feed Coco for 5 days with the oats he has left.
To find out how many days Stefan can feed Coco with the oats he has left, we need to subtract the amount of oats used for the granola bars from the total amount of oats.
Stefan has 4 1/2 cups of oats, which can also be written as 9/2 cups.
He uses 3 1/4 cups of oats for the granola bars, which can also be written as 13/4 cups.
To subtract fractions, we need a common denominator. In this case, the common denominator is 4.
9/2 - 13/4
To have a common denominator, we multiply the first fraction's numerator and denominator by 2:
(9/2) * (2/2) = 18/4
Now, we can subtract the fractions:
18/4 - 13/4 = 5/4
So, Stefan has 5/4 cups of oats left.
Coco needs 1/4 of a cup of oats each day.
To find out how many days Stefan can feed Coco, we divide the amount of oats left by the amount Coco needs each day:
(5/4) ÷ (1/4) = 5/1
Therefore, Stefan can feed Coco for 5 days with the oats he has left.
