conversations.value: Can you walk me through the solution of: Joseph had 16 baseball cards. He gave 3/8 of the cards to his brother and 2 cards to his brother. What percentage of the cards is left to Joseph?
conversations.from: assistant
conversations.value: Joseph gave 16 x 3/8 = 6 cards to his brother.
  He gave a total of 6 + 2 = 8 cards to his brother and friend.
  Joseph has 16 - 8 = 8 cards left.
  This is 8/16 x 100% = 50% of his cards.
