conversations.value: Please show me the solution for: A store received 20 pallets of paper products to stock. Half the pallets were paper towels, a quarter were tissues, and a fifth were paper plates. The rest were paper cups. How many pallets of paper cups did the store receive?
conversations.from: assistant
conversations.value: The store received 20 / 2 = 10 pallets of paper towels.
  They received 20 / 4 = 5 pallets of tissues.
  They received 20 / 5 = 4 pallets of paper plates.
  Thus, the store received 20 - 10 - 5 - 4 = 1 pallet of paper cups.
