Пошаговое объяснение:

а) 4 1/3 + 1/6 = 4 2/6 + 1/6 = 4 3/6 = 4 1/2

б) 5 - 2 2/5 = 4 5/5 - 2 2/5 = 2 3/5

в) 2 1/8 * (-2) = 17/8 * (-2) = - 34/8 = -4 2/8 = -4 1/4

г) 3 1/3 : (-5) = 10/3 * (-1/5) = - 10/15 = - 2/3

д) -2 1/2 + 4/5 = -2 5/10 + 8/10 = -25/10 + 8/10 = -17/10 = -1 7/10

е) -1 3/4 - 2 1/4 = -3 4/4 = -4

ж) 3 3/4 * (-2/15 ) = 15/4 * (-2/15) = - 2/4 = - 1/2

з) -2 1/4 : (-2 7/10) = -9/4 : (-27/10) = -9/4 * (-10/27) = -1/2 * (-5/3) = 5/6

и) - 1 2/7 * 0 = 0
