Mom ordered pizza for my friends and me last night. we ate 3/4 of the pepperoni pizza, 1/3 of the cheese pizza, and 3/8 of the sausage pizza. how much pizza was left for mom to wrap up and put away?

plz answer

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%)
