conversations.value: I would love to understand how to solve this problem: Anton has three times as many cards in his collection as Heike does. Ann has six times as many cards as Heike does. If Ann has 60 cards, how many more cards does Ann have more than Anton?
  Can you explain?

conversations.value: If Ann has 60 cards, which is six times as many cards as Heike, Heike has 60/6= 10 cards.
  Anton has three times as many cards in his collection as Heike does, and since Heike has 10 cards, Anton has 10*3=30 cards.
  Ann has 60-30=30 more cards than Anton.
