Приведем дроби к общему знаменателю и сравним:

1) 1/8 < 3/7:

1/8 = 7/56;

3/7 * 8/8 = 24/56.

2) 2/3 > 1/8;

2/3 = (2 * 8) / 24 = 16/24;

1/8 = 3/24.

3) 3/9 > 1/8;

3/9 = (3 * 8) / 72 = 24/72;

1/8 = 9/72.

4) 2/3 > 5/8;

2/3 = (2 * 8) / 24 = 16/24;

5/8 = (3 * 5) / 24 = 15/25.

5) 5/14 > 1/4;

5/14 = (5 * 2) / 28 = 10/28;

1/4 = 7/28.

6) 13/30 < 7/15;

7/15 = (7 * 2) / 30 = 14/30.

7) 7/15 > 3/10

7/15 = (2 * 7) / 30 = 14/30;

3/10 = (3 * 3) / 30 = 9/30.

8) 1/8 < 1/5;

1/8 = 5/40;

1/5 = 8/40.

9) 21/11 > 11/21;

21/11 = 1 10/11.

10) 6/25 < 11/35;

6/25 = (6 * 7) / 175 = 42/175;

11/35 = (11 * 5) / 175 = 55/175.
