Пошаговое объяснение:
1) 12 1/8 - 5 5/16 = 12 2/16 - 5 5/16 = 6 13/16
2) 6 13/16 + 3 1/4 = 6 13/16 + 3 4/16 = 9 17/16 = 10 1/16
3) 10 1/16 : (-13 5/12) = 161/16 * (-12/161) = -3/4
4) -3/4 + 6,35 = -3/4 + 6 7/20 = 6 7/20 - 15/20 = 5 12/20 = 5 3/5
5) 2 2/3 + 3/5 = 2 10/15 + 9/15 = 2 19/15 = 3 4/15
6) 3 4/15 * (-2 1/7) = 49/15 * (-15/7) = -7
7) 5 3/5 : (-7) = 28/5 * (-1/7) = -4/5
