Пошаговое объяснение:
А)
3/8 + х = 11/8
х = 11/8 - 3/8
х = 8/8
х = 1
Б)
14/33 - х = 1/33
х = 14/33 - 1/33
х = 13/33
В)
(65/112 + р) - 25/112 = 49/112
65/112 + р = 49/112 + 25/112
65/112 + р = 74/112
р = 74/112 - 65/112
р = 9/112
Г)
43/51 - (b - 1/51) = 42/51
b - 1/51 = 43/51 - 42/51
b - 1/51 = 1/51
b = 1/51 + 1/51
b = 2/51
