Answer:
Luis is correct.
Step-by-step explanation:
We see that,
Tito ate of cheese pizza, of pepperoni pizza and of the mushroom pizza.
So, in total Tito ate = = parts of the three pizza's.
Further, Luis ate of cheese pizza and of the mushroom pizza.
So, in total Luis ate = = parts of the three pizza's.
Therefore, we can that both Tito and Luis ate part of the pizza.
Hence, Luis is correct that they both ate the same amount of the pizza.
