1. 19 1/11
2. 47 1/6
Пошаговое объяснение:
1) 40 + 6 1/9 : 2 1/27 - 23 10/11 = 40 + 55/9 : 55/27 - 23 10/11 =
40 + 55/9 * 27/55 - 23 10/11 = 40 + 3 - 23 10/11 = 43 - 23 10/11 = 19 1/11
2) 53,5 - 14 1/6 * 1 1/17 + 8 2/3 = 53 1/2 - 85/6 * 18/17 + 8 2/3 =
53 1/2 - 15 + 8 2/3 = 38 1/2 + 8 2/3 = 38 3/6 + 8 4/6 = 46 7/6 = 47 1/6
