2/3 of a pizza was left over. A group of friends divided the leftover pizza into pieces each equal to 1/18 of the original pizza. After each friend took one piece, 1/6 of the leftover pizza remained. How many friends were in the group?
There was 10 friends because there if you times 2/3 by 6 you get 12/18 and 10 people eat it then there is 3/18 left and after you simpfly it you get 1/6
