Krystal has 7 lbs of fresh dewberries. She uses 2/3 lb of dewberries to make a pint

Question

3of dewberry jam. Krystal only uses the dewberries needed to make whole pints of jam and she makes as many pints as possible.

How many pounds of dewberries will Krystal have left over?

Answer 1

To find out how many pints of jam Krystal can make, divide the total weight of dewberries by the amount of dewberries needed for one pint of jam:

7 lbs / (2/3 lb/pint) = 10.5 pints

Since Krystal can only make whole pints of jam, she can make 10 pints of jam.

To find out how many pounds of dewberries she used to make the jam, multiply the weight per pint by the number of pints made:

(2/3 lb/pint) * 10 pints = 20/3 lbs of dewberries

To find out how many pounds of dewberries she has left over, subtract the amount used from the total amount:

7 lbs - 20/3 lbs = 21/3 lbs - 20/3 lbs = 1/3 lbs.

So Krystal has 1/3 pounds of dewberries left over.
