conversations.value: Can you explain how to solve this math problem: Hannah hangs a 2 foot by 4 foot painting on a 5 foot by 10 foot wall. What percentage of the wall is taken up by the painting?
conversations.from: assistant
conversations.value: First find the area of the painting: 2 feet * 4 feet = 8 square feet
  Then find the area of the wall: 5 feet * 10 feet = 50 square feet
  Then divide the area of the painting by the area of the wall and multiply by 100% to express the answer as a percentage: 8 square feet / 50 square feet * 100% = 16%
