Ответ:
3 2/3
Пошаговое объяснение:
9 9/10 : (79 3/16-1 1/12-77 1/2 + 2 19/48)·(37 41/45-36 4/5) = 3 2/3
1) 79 3/16 - 1 1/12 = 79 9/48 - 1 4/48 = 78 5/48
2) 78 5/48 - 77 1/2 = 78 5/48 - 77 24/48 = 29/48
3) 29/48 + 2 19/48 = 2 48/48 = 3
4) 37 41/45 - 36 4/5 = 37 41/45 - 36 36/45 = 1 5/45 = 1 1/9
5) 9 9/10 : 3 = 3 3/10
6) 3 3/10 * 1 1/9 = 33/10 * 10/9 = 11/3 = 3 2/3
