Mr Fairfax ordered 3 large pizzas for a class party. group A ate 6/6 of the first pizza, and group B ate 8/6 of the remaining pizza. During the party, the class discussed which group ate more pizza. Later, Group C ate all remaining slices of pizza. What fraction of the pizza did Group C eat? Use words and pictures to explain your answer.

Answer 1

Group A ate 6/6 (or 1 whole pizza) of the first pizza. This means there were 0 slices left for Group B.

Group B then ate 8/6 (or 1 and 1/3) of the remaining pizza. This means there were 2/3 of a pizza left.

Group C then ate all the remaining slices of pizza, which is 2/3 of a pizza.

Therefore, Group C ate 2/3 of the pizza.

To represent this visually, we can draw 3 pizzas. The first pizza is whole, representing the pizza group A ate. The second pizza is divided into slices, with 8 slices eaten by group B and 2 slices left. The third pizza is also divided into slices, representing the 2/3 of a pizza that Group C ate.

So group C ate 2/3 of the pizza.
