Keisha makes a large sandwich for a family picnic. she takes 1/2 of the sandwich to the picnic. at the picnic, her family eats 3/8 of the whole sandwich .what fraction of the whole sandwich does keisha bring back from the picnic

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

Step-by-step explanation:

To start, take a whole sandwich 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
