(Subtraction and division are performed in the same way as above.) 68 × 25 = 68 × 40 = What is 10% of 200? 68 * 25 = The first figure (68) 40 = becomes the constant. 200 * 10 % 1,700. 2,720. 20. What percentage is 9 of 36? 9 / 36 % 25. 200 + (200 × 10 %) = 500 - (500 × 20 %) = (43)2 = 200 + 10 % 500 - 20 % 4 * = = * = 220. 400. 4,096. 1/8 8 / = 0.125 25 × 5 = -) 84 ÷ 3 = +) 68 + 17 = (Total) = 135 × (12 + 14) = (12 + 14) ÷ 5 = @ @ 25 * 5 $ 84 / 3 # 68 + 17 $ @ @ @ 12 + 14 $ 135 * @ = @ / 5 = @ @ b M 125.
