в) 7/41
г) 13/19
Пошаговое объяснение:
в) 37/41 – (25/41 + (17/41 – X)) = 2/41
37/41 – 2/41 = 25/41 + (17/41 – X)
35/41 - 25/41 = 17/41 – X
10/41 = 17/41 – X
X = 17/41 – 10/41
X = 7/41
г) 4/19 + (11/19 – (X – 1/19)) = 3/19
4/19 + (11/19 – X + 1/19) = 3/19
4/19 + 12/19 – X = 3/19
16/19 – 3/19 = X
X = 13/19
