Answer 1

Ответ:

Пошаговое объяснение:

1)

6. 11/15 - 2. 7/10 =

6. 22/30 - 2. 21/30 = 4. 1/30

3)

6. 8/12 + 9. 7/18 =

6. 24/36 + 9. 14/36 =

15. 40/36 = 16. 4/36 = 16. 1/9

4)

4. 7/12 + 3. 5/24 =

4. 14/24 + 3. 5/24 = 7. 19/24

5)

6. 3/8 - 2. 5/9 =

6. 27/72 - 2. 40/72 =

5. 99/72 - 2. 40/72 =

3. 59/72

6)

9. 1/21 - 5. 16/63 =

9. 3/63 - 5. 16/63 =

8. 66/63 - 5. 16/63 = 3. 50/63

Answer 2

Я могу помочь вам решить эти задачи по арифметике. Вот подробные ответы:

1) 6 + 11/15 - 2 + 7/10 = (6 - 2) + (11/15 + 7/10) = 4 + (22/30 + 21/30) = 4 + (43/30) = 4 + 1 + 13/30 = 5 + 13/30

2) 6 + 8/12 + 9 + 7/18 = (6 + 9) + (8/12 + 7/18) = 15 + (12/18 + 7/18) = 15 + (19/18) = 15 + 1 + 1/18 = 16 + 1/18

3) 4 + 7/12 + 3 + 5/24 = (4 + 3) + (7/12 + 5/24) = 7 + (14/24 + 5/24) = 7 + (19/24)

4) 6 + 3/8 - 2 + 5/9 = (6 - 2) + (3/8 + 5/9) = 4 + (27/72 + 40/72) = 4 + (67/72)

5) 9 + 1/21 - 5 + 16/63 = (9 - 5) + (1/21 + 16/63) = 4 + (3/63 + 16/63) = 4 + (19/63)
