Пошаговое объяснение:
(3/4 + 1/6) * 3 + (5/6 - 1/2) : 2/9 = 4 1/4
3/4 + 1/6 = (9+2) / 12 = 11/12
11/12 * 3 = 11/4
5/6 - 1/2 = (5-3) / 6 = 2/6 = 1/3
1/3 : 2/9 = 1/3 * 9/2 = 3/2
11/4 + 3/2 = (11+6) / 4 = 17/4 = 4 1/4
(1 1/5 + 2 3/10) : 1/2 + (6 3/4 - 2 2/3) : 1 1/6 =
1 1/5 + 2 3/10 = 6/5 + 23/10 = (12+23) / 10 = 35/10 = 7/2
7/2 : 1/2 = 7/2 * 2/1 = 7
6 3/4 - 2 2/3 = 27/4 - 8/3 = (81-32) / 12 = 49/12
49/12 : 1 1/6 = 49/12 : 7/6 = 49/12 * 6/7 = 7/2 = 3 1/2
7 + 3 1/2 = 10 1/2
