Question

Mark uses 3 1/8 pounds of seed to fill the birdfeeders in his backyard, but he only has 1 1/2 pounds of seeds.

Part A
How much seed does he need to buy?

Answer 1

1 5/8 pound.

Explanation:

Convert 1/2 into 1/8's.

1/2 = 4/8.

We now have 1 4/8.

Subtract that from 3 1/8.

3 1/8

- 1 4/8

-----------

1 5/8

Your answer is 1 5/8 pound.

Hope this helps. Have a nice day.
