conversations.value: On the first day, Tobias ate 2/5*60 = 24 pieces of the pizza.
  On the second day, Tobias ate 10 more pieces of the pizza, totaling 24+10 = 34 pieces
  The number of pieces of pizza remaining is 60-34 = 26
  On the third day, Tobias ate 7/13*26 = 14 pieces of pizza.
  So far, he has eaten 14+34 = 48 pieces of the pizza he bought.
