Lou eats 6/8 of a pizza what fraction of the pizza, in simplest form is left over

1/4 of the pizza is left over.

Explanation:

First, we want to find how much is left over. To do this, we subtract the whole pizza by how much he ate. So 8/8 - 6/8 = 2/8. Now, we have to simplify 2/8. The GCF (Greatest Common Factor) of 2 and 8 is 2, so we divide 2/2 and 8/2. We get 1/4, therefore that is the answer.

2/8 = 1/4 of the pizza left over
