Answer:
5/6 and 1/6
Step-by-step 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
