conversations.value: I'm completely lost with this math problem: Marla is mixing a particular shade of lilac that's 70% blue paint, 20% red paint, and the rest white paint. If she adds 140 ounces of blue paint, how many ounces of white paint does she add?
  Can you give me a hand?

conversations.value: First find the total amount of paint Marla mixes by dividing the amount of blue paint by the percentage of the paint that's blue: 140 ounces / .7 = 200 ounces
  Then multiply the total amount of paint by the percentage that's white to find the number of white ounces: 200 ounces * 10% = 20 ounces
