1) 54 / 72 = (3 * 18) / (24 * 3) = (1 * 18) / (24 * 1) = 18 / 24 = (6 * 3) / (6 * 4) = (1 * 3) / (1 * 4) = 3 / 4

2) 56 / 68 = (28 * 2) / (34 * 2) = 28 * 1 / (34 * 1) = 28 / 34 = 14 * 2 / (17 * 2) = 14 * 1 / (17 * 1) = 14 / 17

3) 18 / 64 = 9 * 2 / (2 * 32) = 9 * 1 / (1 * 32) = 9 / 32

4) 81 / 54 = (27 * 3) / (18 * 3) = 27 * 1 / (18 * 1) = 27 / 18 = (9 * 3) / (9 * 2) = 1 * 3 / (1 * 2) = 3 / 2

5) 24 / 36 = 12 * 2 / (2 * 18) = 12 * 1 / (1 * 18) = 12 / 18 = (6 * 2) / (6 * 3) = 1 * 2 / (1 * 3) = 2 / 3
