conversations.value: I would love to understand how to solve this problem: Mary bought a packet of 1500 stickers. She shared them between Susan, Andrew and Sam in the ratio 1:1:3 respectively. If Sam gave Andrew two-thirds of his own share, how many stickers does Andrew now have?
  Can you explain?
conversations.from: assistant
conversations.value: The sum of the ratio is 1+1+3 = 5, therefore each part is 1500/5 = 300 stickers
  Sam got 3 parts for a total of 3*300 = 900 stickers
  He gave two-thirds of this which is 900*(2/3) = 600 stickers to Andrew
  Andrew had one part already, which is 1*300 = 300
  Andrew now has a total of 300+600 = 900 stickers.
