Пошаговое объяснение:
1/4 - (1 - 11/12) = 1/4 - ( 12/12 - 11/12) = 1/4 - 1/12 = 3/12 - 1/12 = 2/12 = 1/6
-------------------------------------------------------------------------------------------------
2 - (13/33 - 5/22) = 2 - (26/66 - 15/66) = 2 - 11/66 = 1 66/66 - 11/66 = 1 55/66
= 1 5/6
--------------------------------------------------------------------------------------------------
6 3/16 - (2 3/8 + 3 5/12) = 6 3/16 - (2 9/24 + 3 10/24) = 6 3/16 - 5 19/24 = 6 9/48 - 5 38/48 = 5 57/48 - 5 38/48 = 19/48
