Пошаговое объяснение:
1) 28 : 1. 3/4 = 28 : 7/4 = 28 * 4/7 = 4 * 4 / 1 = 16/1 = 16
2) 1. 1/3 : 22 = 4/3 : 22 = 4/3 * 1/22 = 2/3 * 1/11 = 2/33
3) 1. 2/3 * 9. 3/11 = 5/3 * 102/11 = 5/1 * 34/11 = 170/11 = 15. 5/11
4) 4 : 1. 1/2 = 4 : 3/2 = 4 * 2/3 = 8/3 = 2. 2/3
5) 16 + 2/33 + 15. 5/11 + 2. 2/3 =
16 + 2/33 + 15. 15/33 + 2. 22/33 = 33. 39/33 =
34. 6/33 = 34. 2/11
6) 34. 2/11 * 3. 1/7 = 376/11 * 22/7 = 376/1 * 2/7 = 752/7
Это числитель
7) 47 * 2/7 = 94/7 = 13. 3/7
8) 67. 1/7 - 13. 3/7 = 66. 8/7 - 13. 3/7 = 53. 5/7
Это знаменатель
9) 752/7 : 53. 5/7 = 752/7 : 376/7 = 752/7 * 7/376 = 752/376 = 2
