7 4/9+3 5/9-2 1/7
4 7/45+13 3/4+2 3/4+2 38/45​

Answer 1

9 1/10-(4 5/11 + 6/11 )=9

74/9+35/9-21/7 =8

47/45+13 3/4+23/4+238/45=345

Answer 2

Пошаговое объяснение:

№1

1) 4. 5/11 + 2. 6/11 = 6. 11/11 = 7

2) 9. 1/10 - 7 = 3. 1/10

№2

1) 7. 4/9 + 3. 5/9 = 10. 9/9 = 11

2) 11 - 2. 1/7 = 10. 7/7 - 2. 1/7 = 8. 6/7

№3

1) 4. 7/45 + 2. 38/45 = 6. 45/45 = 7

2) 13. 3/4 + 2. 3/4 = 15. 6/4 = 16. 2/4 = 16. 1/2

3) 7 + 16. 1/2 = 23. 1/2
