Ответ:

Пошаговое объяснение:

1) 3. 1/2 + 5. 2/7 = 3. 7/14 + 5. 4/14 = 8. 11/14

2) 4. 2/5 + 9. 3/10 = 4. 4/10 + 9. 3/10 = 13. 7/10

3) 2. 7/9 + 4. 5/6 = 2. 28/36 + 4. 30/36 = 6. 58/36 = 7. 22/36 = 7. 11/18

4) 8. 3/10 + 21. 7/8 = 8. 12/40 + 21. 35/40 = 29. 47/40 = 30. 7/40

5) 2. 3/5 + 1. 3/10 = 2. 6/10 + 1. 3/10 = 3. 7/10

6) 3. 5/9 + 4. 2/3 = 3. 5/9 + 4. 6/9 = 7. 11/9 = 8. 2/9

7) 6. 3/5 + 1. 7/18 = 6. 54/90 + 1. 35/90 = 7. 89/90

8) 4. 3/8 + 8. 1/6 = 4. 9/24 + 8. 4/24 = 12. 13/24

9) 7. 5/22 + 3. 4/11 = 7. 5/22 + 3. 8/22 = 10. 13/22

Answer 3

1) 3 + 1/2 + 5 + 2/7 = 3 + 5 + 1/2 + 2/7 = 8 + 1/2 + 2/7 = 8 + 7/14 + 4/14 = 8 + 11/14 = 8 + 5/7

2) 4 + 2/5 + 9 + 3/10 = 4 + 9 + 2/5 + 3/10 = 13 + 2/5 + 3/10 = 13 + 4/10 + 3/10 = 13 + 7/10

3) 2 + 7/9 + 4 + 5/6 = 2 + 4 + 7/9 + 5/6 = 6 + 7/9 + 15/9 = 6 + 22/9 = 6 + 2 4/9

4) 8 + 3/10 + 21 + 7/8 = 8 + 21 + 3/10 + 7/8 = 29 + 3/10 + 7/8 = 29 + 24/80 + 87/80 = 29 + 111/80 = 29 + 1 31/80

5) 2 + 3/5 + 1 + 3/10 = 2 + 1 + 3/5 + 3/10 = 3 + 3/5 + 3/10 = 3 + 6/10 + 3/10 = 3 + 9/10 = 3 9/10

6) 3 + 5/9 + 4 + 2/3 = 3 + 4 + 5/9 + 2/3 = 7 + 5/9 + 6/9 = 7 + 11/9 = 7 + 1 2/9

7) 6 + 3/5 + 1 + 7/18 = 6 + 1 + 3/5 + 7/18 = 7 + 3/5 + 7/18 = 7 + 10/18 + 35/90 = 7 + 5/9 + 7/18 = 7 + 20/36 + 14/36 = 7 + 34/36 = 7 + 17/18 = 7 17/18

8) 4 + 3/8 + 8 + 1/6 = 4 + 8 + 3/8 + 1/6 = 12 + 3/8 + 4/24 = 12 + 3/8 + 1/6 = 12 + 9/24 + 4/24 = 12 + 13/24 = 12 + 13/24

9) 7 + 5/22 + 3 + 4/11 = 7 + 3 + 5/22 + 4/11 = 10 + 5/22 + 8/22 = 10 + 13/22
