Question

Keisha bakes a pan of brownies for family picnic. She takes 1/2 of the brownies to the picnic. At the picnic, her family eats 3/8 of the whole pan of brownies. Which fraction of the whole pan of brownies does Keisha bring back from the picnic?

Answer 1

Keisha has 1/8th of the brownie pan that she brings back.

Explanation:

To start, take a whole pan and subtract the 1/2 she left at home and the 3/8 that her family ate.

1 - 1/2 - 3/8 = Leftover

We also need to give them common denominators to complete the action.

8/8 - 4/8 - 3/8 = Leftover

1/8 = Leftover
