conversations.value: Solve the following math problem: Ali is collecting bottle caps. He has 125 bottle caps. He has red ones and green ones. If he has 50 red caps, what percentage of caps are green?
conversations.from: assistant
conversations.value: He has 75 green caps because 125 - 50 = 75
  The proportion of caps that are green is .6 because 75 / 125 = .6
  The percentage that are green is 60 because .6 x 100% = 60%
