conversations.value: I'm completely lost with this math problem: Prince is a butcher. He sells 15kg of meat every hour he works, and he works 10 hours a day. His friend Bill gives him a bull that weighs 750kg. How many days will it take Prince to sell the meat from Bill's bull?
  Can you give me a hand?

conversations.value: In a day Bill sells 15 * 10 = 150kg of meat.
  It will take Bill 750 / 150 = 5 days to sell all the meat from the bull.
