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? Give me reasons, before answering the question

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. So the final answer is 50.
