Пошаговое объяснение:
a) 3 2/3 + 1/9 = 3 6/9 + 1/9 = 3 7/9
б) 3 - 1 1/7 = 2 7/7 - 1 1/7 = 1 6/7
в) -5 * 3 3/10 = -5 * 33/10 = -33/2 = -16 1/2
г) 2 2/3 : (-4) = 8/3 * (-1/4) = -2/3
д) -3 1/2 + 2 5/6 = -3 3/6 + 2 5/6 = -4/6 = -2/3
e) -1 2/3 - 2 1/3 = -3 3/3 = - 4
ж) 1 1/5 * (-5/12) = 6/5 * (-5/12) = - 1/2
з) -3 1/9 : (-1 1/6) = -28/9 : (-7/6) = 28/9 * 6/7 = 8/3 = 2 2/3
и) -2 3/5 * 0 = 0
