Question

Matt had 15/16 pound of dog food in a bag.

He fed his puppy pound of the food.
How much dog food is left in the bag?

Answer 1

7/16

Explanation:

15/16 lb. is the beginning amount. We are taking away 1/2 lb.

15/16 - 1/2

= 15/16 - 8/16

= 7/16

1/2 and 8/16 are the same. We use 8/16 bc we need a common denominator (same bottom number).

Then when subtracting fractions with a common denominator, you subtract the tops and keep the same bottom.
