Cheese pizzas are 2/3 of the pizza's purchased because 2 / (2+1) = 2/3

She buys 4 cheese pizzas because 6 x (2/3) = <<6*2/3=4>>4

These give her 72 pieces of cheese pizza because 4 x 18 = <<4*18=72>>72

The students at 64 pieces of cheese because 72 - 8 = <<72-8=64>>64

There are 32 students in her class because 64 / 2 = <<64/2=32>>32

A large pizza has 18 slices. She orders 6 total pizzas and there are 8 pieces of cheese and 4 pieces of onion leftover. How many students are in the class?
