2/3 + 1/6=5/6

Answer: 2 ounces

Step-by-step explanation:

I'm assuming you meant to write the fractions 1/6 and 2/3.

If so, then they add to...

1/6 + 2/3 = 1/6 + 4/6 = 5/6

Meaning that they collectively ate 5/6 of the box. That leaves 1/6 of the box leftover. The fractions 5/6 and 1/6 add to 1.

Then take 1/6 of the 12 ounce figure to get (1/6)*12 = 12/6 = 2 ounces
