A group of 6 students are studying chemistry and want to take a pizza break. Each student wants 3 slices of pizza. One pizza contains 8 slices. How many
pizzas should the students order? (You may have fractional/decimal quantities
of pizza.)

3 pizzas.

Explanation:

8 • 3 = 24

24 • 6 = 4

Each student can have up to 4 pizzas.

2.25 Pizzas

Explanation:

Number of slices they need is number of students (6) multiplied by number of slices (3) each wants.  6*3= 18

To figure out how many Pizzas will have that many slices divide number of slices they want by number of slices per pizza. 18/8 = 2.25
