Tyler and Dean ordered Pizza. Tyler
ate 1/2 of the pizza and Dean ate 1/3 of the
pizza. How much of the pizza was eaten, and
how much is left?

5/6 and 1/6

Explanation:

Let x represent the part that is eaten by Tyler and y represent the part that is eaten by Dean. Then, the total eaten part of the pizza is represented by x+y

Since Tyler ate 1/2 of the pizza, x=1/2 and Dean ate 1/3 of the pizza y=1/3. Then total eaten part of the pizza is x+y = 1/2 + 1/3 = 5/6

Since total of the pizza is equal to 1, the left part is 1 - 5/6 = 1/6
