My three best friends and I ran into the house after school.
We were all hungry, and looking forward to a piece of Mom's
cherry pie. There was only half of the pie left in the frig. We
polished that off, and each of us got the same amount.
How much of a whole pie did each of us get.
Me + 3 best friends = 4 guys
(1/2 pie) / (4 guys) = 1/8 pie per guy .
