Представим число в виде дроби с указанным знаменателем 9:

1) 17/51 = 17 / (17 * 3) = 1 / (1 * 3) = 1/3 = 1 * 3 / (3 * 3) = 3/9;

2) 12/27 = (4 * 3) / (9 * 3) = (4 * 1) / (9 * 1) = 4/9;

3) 1/3 = (1 * 3) / (3 * 3) = 3/9;

4) 10/15 = (2 * 5) / (3 * 5) = (2 * 1) / (3 * 1) = 2/3 = (2 * 3) / (3 * 3) = 6/9;

5) 2 4/12 = 2 1/3 = (2 * 3 + 1) / 3 = 7/3 = (7 * 3) / (3 * 3) = 21/9;

6) 16/18 = (2 * 8) / (2 * 9) = 8/9;

7) 2/6 = 1/3 = 3/9;

8) 20/36 = (4 * 5) / (9 * 4) = 5/9;

9) 15/27 = (3 * 5) / (3 * 9) = (1 * 5) / (1 * 9) = 5/9;

10) 26/39 = (2 * 13) / (3 * 13) = 2/3 = (2 * 3) / (3 * 3) = 6/9;

11) 7/21 = 7 / (7 * 3) = 1/3 = (1 * 3) / (3 * 3) = 3/9;

12) 1 1/3 = 4/3 = (4 * 3) / (3 * 3) = 12/9.
