First of all, put your own pizza away, kid.
Second, you have left 1/4 left of the pepperoni, 2/3 left of the cheese, and 5/8 left of the sausage. You gotta find the common denominator, right? because you have 4, 3, and 8 as denominators, that is gonna be 24. So 1/4 turns into 6/24, 2/3 turns into 16/24, and 5/8 turns into 15/24. Add it all up. you've got 44/72 of the original pizza left, which simplifies to 22/36, and again to 11/18 (or 61%)
