if 4 people share three brownies so each person gets the same amount, how much brownie will each person get.

Simple, divide the 3 brownies by four people.

3/4=.75. each person gets 3 quarters of a brownie

Answer:3 quarters each 3/4

Cut each brownie into 4 equal squares ... each square would be 1/4 ... by doing this you have 12 squares or 12 quarter brownies. So that each person gets the same amount ... take 12 which is the total amount of brownie squares and divide into the amount of people. 12:4=3. Therefore each person will get 3 squares each which is 3/4 of a brownie
