6 3/5-х=2 2/15
х=6 3/5-2 2/15
х=6 9/15-2 2/15
х=4 7/15
Ответ:4 7/15
б)
3 1/7+х=9 1/2
х=9 1/2-3 1/7
х=9 7/14-3 2/14
х=6 5/14
Ответ:6 5/14
в)
х-5 7/9=4 1/3
х=5 7/9+4 1/3
х=5 7/9+4 3/9
х=9 10/9
х=10 1/9
Ответ:10 1/9
Пошаговое объяснение:
6 3/5 - х = 2 2/15
х = 6 3/5 - 2 2/15
х = 6 9/15 - 2 2/15
х = 4 7/17
3 1/7 + х = 9 1/2
х = 9 1/2 - 3 1/7
х = 9 7/14 - 3 2/14
х = 6 5/14
х - 5 7/9 = 4 1/3
х = 4 1/3 + 5 7/9
х = 4 3/9 + 5 7/9
х = 9 10/9
х = 10 1/9
