conversations.value: Kimberly went hiking and took a 4-liter bottle full of water with her. The first time she drank from it, she consumed a quarter of the water in the bottle. Later on, she drank 2/3rd of the remaining water. How much water is left in the bottle (in liters)?
  What is the solution?

conversations.value: Her first drink consumed 1/4 * 4 = 1 liter of water.
  Thus there were 4 - 1 = 3 liters of water left in the bottle.
  Next, she drank 2/3 * 3 = 2 liters.
  Thus, there were 3 - 2 = 1 liters remaining.
