conversations.value: TreShaun's full marker has enough ink in it to paint three 4 inch by 4 inch squares. If he colors in two 6 inch by 2 inch rectangles, what percentage of ink is left?
  Solve it.

conversations.value: Each 4 by 4 square equals 16 square inches because 4 x 4 = 16
  Three squares equals 48 square inches because 3 x 16 = 48
  Each rectangle uses 12 square inches because 2 x 6 = 12
  Both rectangles will use 24 square inches because 2 x 12 = 24
  He has 1/2 of the ink left because 24 / 48 = 1/2
  He has 50% of the ink left because 1/2 x 100 = 50
