Пошаговое объяснение:
1) 1. 9/16 * 3. 1/5 = 25/16 * 16/5 = 25/5 = 5
2) 9 : 2. 2/5 = 9 : 12/5 = 9 * 5/12 = 45/12 = 15/4 = 3. 3/4
3) 5 + 1. 2/3 = 6. 2/3
4) 6. 2/3 - 3. 3/4 = 6. 8/12 - 3. 9/12 = 5. 20/12 - 3. 9/12 = 2. 11/12
5) 17. 7/16 - 6. 1/5 = 17. 35/80 - 6. 16/80 = 11. 19/80
6) 2. 11/12 : 11. 19/80 = 35/12 : 899/80 = 35/12 * 80/899 = 35/3 * 20/899 = 700/2697
