Пошаговое объяснение:

8) 5/12 + 1/8 / 3/8 = 10/24 + 3/24 / 3/8 = 13/24 / 3/8 = 13/24 * 8/3 = 13/9.

9) 2 6/7 / (5/16 - 9/14) = 20/7 / ( 35/42 - 27/42) = 20/7 / 8/42 = 20/7 *48/8 = 120/8 = 15/1.

11) 2 1/4 / 1 4/11 - 3/8 / 7/8 = 9/4 / 15/11 - 3/8 / 7/8 = 9/4 * 11/15 - 3/8 * 8/7 = 99/45 - 3/7 = 693/315 - 145/315 = 548/315.
