conversations.value: I'm completely lost with this math problem: Carla's sheepdog rounded up 90% of her sheep, but the remaining 10% wandered off into the hills. If there are 81 sheep in the pen, how many are out in the wilderness?
  Can you give me a hand?

conversations.value: First find the total number of sheep by dividing the number rounded up by 90%: 81 sheep / .9 = 90 sheep
  Then multiply that number by 10% to find the number that are in the hills: 90 sheep * 10% = 9 sheep
