Answer: everyone gets 1/4 of the pizza.
Step-by-step explanation: you can convert the 3/4 to .75 and divide that by 3. or you can think about it as the pizza is a dollar and the slices are quarters/ 25 cents. OOOO those are your 4 quarters that make up a dollar/ pizza. OOO those are the 3/4 of the pizza left. if there are 3 people each gets a quarter/ fourth of a pizza. so the answer is 1/4.
