Mario ordered a pizza for dinner when it arrived, mario quickly ate 1/8 of the pizza. while mario went to go get napkins, his pet poodle ate 1/3 of the pizza.

a. about what percent of the pizza is left

1/8 of the pizza is about 12% and 1/3 is about 33%. So if 45% of the pizza was eaten by Mario and his dog, there is about 55% left.

(If 1/4 means 25% then 1/8 is half of that 12.5% exactly but I used 12% since we are estimating)
