conversations.value: I need help with this problem:
  Fabian has three times more marbles than Kyle and five times more than Miles. If Fabian has 15 marbles, how many marbles do Kyle and Miles have together?
conversations.from: assistant
conversations.value: Kyle has a third of Fabian's number of marbles, so he has 15 / 3 = 5 marbles.
  Miles has a fifth of Fabian's number of marbles, so he has 15 / 5 = 3 marbles.
  Miles and Kyle together have 5 + 3 = 8 marbles.
