Пошаговое объяснение:
1.
х = 77 : 11/15 = 77 * 15/11 = 7*15 = 105
2.
х = 92 : 23/28 = 92 * 28/23 = 4 * 28 = 112
3.
х = 25 : 15/64 = 25 * 64/15 = 5*64/3 = 320/3 = 106 целых 2/3
4.
х = 80/9 : 16/3 = 80/9 * 3/16 = 5/3 = 1 целая 2/3
5.
у = 34/5 : 17/5 = 34/5 * 5/17 = 2
6.
у = 57/4 : 19/2 = 57/4 * 2/19 = 3/2 = 1 целая 1/2
