conversations.value: A grocery store has 4 kinds of jelly. They sell grape jelly twice as much as strawberry jelly, and raspberry jelly twice as much as plum jelly. The raspberry jelly sells a third as much as the grape jelly. If they sold 6 jars of plum jelly today, how many jars of strawberry jelly did they sell?
  How to solve this?

conversations.value: They sell twice as much raspberry jelly as plum jelly, so they sold 2 * 6 = 12 jars of raspberry jelly today.
  The raspberry jelly sells a third as much as the grape jelly, so they sold 12 * 3 = 36 jars of grape jelly today.
  The grape jelly sells twice as much as the strawberry jelly, so they sold 36 / 2 = 18 jars of strawberry jelly today.
