C. 5-fourteenths
Explanation: Joanna ate 3/7 of the pizza and Michael ate 2/7 of the pizza. Adding these together, we get 3/7 + 2/7 = 5/7. This means they ate 5/7 of the pizza together. If we express this as a fraction with a common denominator, we get 5/7 = 10/14. So, Joanna and Michael ate 10/14 or 5/14 of the pizza altogether.
Joanna ate 3-sevenths of a pizza. Michael ate 2-sevenths of the pizza.
How much pizza did Joanna and Michael eat altogether?
