conversations.value: If Sophia ate 1/6 of the pie, then 6/6 - 1/6 = 5/6 is left in the fridge.
  Let x be the pie's original weight.
  The current weight of the pie can be described by 5x/6=1200 grams
  So, 5x=7200.
  And, the original weight is x = 1440 grams.
  So, Sophia ate 1440 grams original - 1200 grams after= 240 grams of pie.
