each pizza has 8 slices the teachers want enough pizzas so that each student can have 2 slices if there are 22 students in eeach of the 3 fourth grade classes how many pizzas must be ordered

22 * 3 = 66 students
66 * 2 = 132 pieces
132/8 = 16 1/2
Since the teachers can't buy 1/2 a pizza, they'll need to buy 17 pizzas.
