# Jack has 10 whole pizzas, and he divides each pizza into 8 equal parts. He then puts equal number of parts in 4 boxes. How many whole pizzas do each box have?

$2$ whole pizzas plus 4 slices in each box.
Each pizza is divided into $8$ slices so you get (for $10$ pizzas):
$8 \cdot 10 = 80$ slices:
In $4$ boxes you can put $\frac{80}{4} = 20$ slices correspomding to:
$\frac{20}{8} = 2.5$ which is 2 whole pizzas and 4 spare slices (corresponding to half or 0.5 of a pizza).
