Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
TreShawn's mom needs to order pizza for her son and his two friends. She knows that TreShawn always eats 1/2 a pizza. His friend Michael eats 1/3 of a pizza and his other friend LaMar eats 1/6 of a pizza. How many pizzas does she need to order?

### Response:
She knows that TreShawn and his two friends will eat 1/2 + 1/3 + 1/6 = 11/12 of a pizza
If she orders 1 pizza, they will have leftovers which isn't good because pizza gets cold fast.
She needs to order 1/12 of a pizza more than 11/12, which is 11/12 + 1/12 = 12/12 pizzas
