Agroup orders 3 large veggie pizzas. each slice represents 1/8 of the entire pizza. the group eats 3/4 of the pizza. how many slices of pizza are left? justify your answer.

The first step is to calculate the total number of pizza slices there are.

We know each slice is 1/8 of the pizza.  (think of 1/8 as 1 out of 8 pieces)
This means each pizza has 8 slices. 
There are 3 pizzas so there are 8 x 3 = 24 slices total

Next we want to figure how many slices of pizza they ate which will help us figure out how many are left.

They ate 3/4 of the pizza, so in other words only 1/4 of the pizza is left.

In order to figure out how many slices are left, all we need to do is find out what 1/4 of the total number of slices are.

# of slices left = Total number of slices x 1/4 (1/4 of the pizza is left)

# of slices left = 24 x 1/4 = 24÷4 = 6

This means there are 6 slices of pizza left.
