You can put this solution on YOUR website! So we know that she ordered 2 pizzas which are cut into 8 pieces on each one, so we get 16 pieces of pizzas.
Since Chris got 1/2 of "a" pizza, he got 1/2 times 8 which equals to 4 pizzas
Since John got 3/8 of "a" pizza, he got 3/8 times 8 which equals to 3 pizzas
Since Sally got 1/4 of "a" pizza, she got 1/4 times 8 which equals to 2 pizzas
Since 9 pizzas were taken away, Micelle got 16 - 9 pizzas which is 7 pizzas
Ok so there are 16 slices all together.
(Chris got 1/2 of pizza which is 4 slices.)
16 - 4 = 12 slices.
(John got 3/8 of a pizza which is 3 slices.)
12 - 3 = 9 slices
(Sally got 1/4 of a pizza which is 2 slices.)
9 - 2 = 7 slices.
