Пошаговое объяснение:
1)
2. 1/6 + (-2. 1/4 + (-3. 3/5) ) =
2. 1/6 + (-2. 1/4 - 3. 3/5) =
2. 10/60 + (-2. 15/60 - 3. 36/60) =
2. 10/60 + (-5. 51/60) =
2. 10/60 - 5. 51/60 = -3. 41/60
2)
(16,23 + (-1,7) ) + (-12,41) =
(16,23 - 1,7) - 12,41 =
14,53 - 12,41 = 2,12
3)
(-18,83 + 11,4) + (-23,3 + 19,73) =
-7,43 + (-3,57) = -7,43 - 3,57 = -11
