1/3 of a pizza remains, and Seth and Ethan want to split it evenly. What fraction of the original pizza will each get?

If 8 friends share 2 pizzas, we'll divide.

2 pizzas, divided by 8 friends:

(2 pizzas) / (8 friends) = (2/8) pizzas/friend = (1/4) pizzas per friend

Each friend gets to eat a quarter of a pizza.

Myself, I'm usually satisfied after my second slice.

Pizza sounds pretty good right about now ...
