Пошаговое объяснение:
1) 6 3/11 + х = 10 6/7
х = 10 6/7 - 6 3/11
х = 10 66/77 - 6 21/77
х = 4 45/77
2) 9 5/36 - х = 2 4/9
х = 9 5/36 - 2 4/9
х = 9 41/36 - 2 16/36
х = 8 41/36 - 2 16/36)
х = 6 25/36
3) х- 5 17/60=7 9/20
х= 7 9/20+5 17/60
х=7 27/60+5 17/60
х= 12 44/60
х= 12 11/15
можно и так :)
х = (10 - 6) + (66/77 - 21/77)
х = (8 - 2) + (41/36 - 16/36)
х= 7 9/20 + 5 17/60
х = (7 + 5) + (27/60 + 17/60)
