conversations.value: Can you break down the solution for me for this math problem: Jame is trying to learn to tear playing cards.  He can tear 30 cards at a time.  A new deck of cards has 55 cards if you include the jokers and blank cards.  He tears cards 3 times a week.  If he buys 18 decks how many weeks can he go?

conversations.value: He tears 30*3=90 cards a week
  He bought 55*18=990 cards
  So he can tear for 990/90=11 weeks
