conversations.value: 2 pizzas were ordered and had 12 slices each for a total of 2*12 = 24 slices
  Dean ate 1/2 of a 12 sliced pizza so 12/2 = 6 slices were left over
  Sammy ate 1/3 of a 12 sliced pizza so 12/3 = 4 slices were left over
  Dean ate 6 slices, Sammy ate 4 and Frank had 3 so 6+4+3 = 13
  They started with 24 slices and 13 slices so 24-13 = 11 slices left
