Answer 2

Конечно, давайте решим эти математические задачи:

1. 3/10 + 7/10 = (3 + 7) / 10 = 10/10 = 1

2. 3/4 + 5/8 = (3/4) + (5/8) = (6/8) + (5/8) = 11/8 = 1 3/8

3. 2/5 + 7/15 = (2/5) + (7/15) = (6/15) + (7/15) = 13/15

4. 5/9 - 13/27 = (5/9) - (13/27) = (15/27) - (13/27) = 2/27

5. 2/5 - 3/8 = (2/5) - (3/8) = (16/40) - (15/40) = 1/40

6. 11/12 - 19/60 = (11/12) - (19/60) = (55/60) - (19/60) = 36/60 = 3/5

7. 3/10 + 1/8 = (3/10) + (1/8) = (24/80) + (10/80) = 34/80 = 17/40

8. 3/4 + 5/6 = (3/4) + (5/6) = (9/12) + (10/12) = 19/12 = 1 7/12

9. 9/20 - 13/30 = (9/20) - (13/30) = (27/60) - (26/60) = 1/60

10. 3/8 - 5/24 = (3/8) - (5/24) = (9/24) - (5/24) = 4/24 = 1/6

Вот и все решения. Если у вас есть еще какие-либо вопросы, не стесняйтесь задавать.
