Пошаговое объяснение:
1.
1) 16/27 - 5/9 = 16/27 - 15/27 = 1/27
2) 1/27 * 3/10 = 3/270 = 1/90
2.
1) 5/9 * 3/10 = 15/90 = 1/6
2) 16/27 - 1/6 = 32/54 - 9/54 = 23/54
3.
1) 2. 2/7 * 1. 5/44 = 16/7 * 49/44 = 28/11 = 2. 6/11
2) 6 - 2. 6/11 = 5. 11/11 - 2. 6/11 = 3. 5/11
3) 3. 5/11 * 2. 17/19 =
38/11 * 55/19 = 10
