Answer» (5 + 5/7) / 5 = (1 + 1/7) / 1 = 8/7 (3 + 2/3) / 3 = 1 + 2/9 = 11/9 (8x - (12 + 1/2)) / (7x - (12 + 1/2)) = 11 / 99 * (8x - 12 - 1/2) = 11 * (7x - 12 - 1/2)72x - 108 - 9/2 = 77x - 132 - 11/2132 - 108 + 11/2 - 9/2 =77x - 72x24 + 2/2 = 5x24 + 1 = 5x25 = 5x5 = x 8x = 8 * 5 = 407x = 7 * 5 = 35 40,35 |
