Dario decides to take each one of the 4 pieces and share it equally among the 5 of them. First, he divides one piece into 5 equal parts and shares it, then the next one, and so on.
What fraction of the party size sub did each person get after all the parts were shared out? Briefly explain your reasoning.
Dario divided each of the 4 pieces into 5 equal parts and shared each part among 5 people. So, each person received a total of 5 parts, one from each of the 4 pieces, making it a total of 20 parts. Since there are 5 people, each person received 4 parts out of the 20 parts.
Therefore, each person received 4/20 or 1/5 of the party size sub after all the parts were shared out.
