Pizza Party: Adding and Subtracting Mixed Numbers

Add and subtract pizzas cut into equal slices.

Count the slices

Each pizza is cut into equal slices. Write each answer as a mixed number or a fraction.

1.
Each circle is one pizza cut into 8 equal slices. The shaded parts show the pizza left on the table.


Pizza left:   pizzas

2.
These pizzas are cut into 6 equal slices. Ravi's table has 1 2/6 pizzas. Lena's table has 2 3/6 pizzas. How much pizza do the two tables have in all?

1 2/6 + 2 3/6 =   pizzas

3.
Mia adds 3 1/4 pizzas and 2 2/4 pizzas. Which way of adding is correct?
  • A. 3 + 2 = 5 and 1/4 + 2/4 = 3/8, so the total is 5 3/8.
  • B. 3 − 2 = 1 and 2/4 − 1/4 = 1/4, so the total is 1 1/4.
  • C. 3 + 2 = 5 and 1/4 + 2/4 = 3/4, so the total is 5 3/4.
  • D. Add only the wholes: 3 + 2 = 5, so the total is 5.
