Answer 2

Let's solve each of these equations step by step:

1. 2/3 + 1/5: To add these fractions, you need a common denominator, which is 15. (2/3) * (5/5) + (1/5) * (3/3) = 10/15 + 3/15 = 13/15

2. 3/4 + 1/10: The common denominator here is 20. (3/4) * (5/5) + (1/10) * (2/2) = 15/20 + 2/20 = 17/20

3. 5/8 + 3/10: The common denominator is 40. (5/8) * (5/5) + (3/10) * (4/4) = 25/40 + 12/40 = 37/40

4. 2/7 + 1/3: To add these fractions, you need a common denominator, which is 21. (2/7) * (3/3) + (1/3) * (7/7) = 6/21 + 7/21 = 13/21

5. 1/6 + 1/8: The common denominator here is 24. (1/6) * (4/4) + (1/8) * (3/3) = 4/24 + 3/24 = 7/24

6. 5/8 - 1/3: The common denominator is 24. (5/8) * (3/3) - (1/3) * (8/8) = 15/24 - 8/24 = 7/24

7. 2/3 - 3/10: The common denominator is 30. (2/3) * (10/10) - (3/10) * (3/3) = 20/30 - 9/30 = 11/30

8. 11/12 - 3/8: The common denominator is 24. (11/12) * (2/2) - (3/8) * (3/3) = 22/24 - 9/24 = 13/24

9. 3/4 - 2/7: To subtract these fractions, you need a common denominator, which is 28. (3/4) * (7/7) - (2/7) * (4/4) = 21/28 - 8/28 = 13/28

10. 1/2 + 1/7: The common denominator here is 14. (1/2) * (7/7) + (1/7) * (2/2) = 7/14 + 2/14 = 9/14

11. 2/9 + 3/7: To add these fractions, you need a common denominator, which is 63. (2/9) * (7/7) + (3/7) * (9/9) = 14/63 + 27/63 = 41/63

12. 8/9 - 2/7: To subtract these fractions, you need a common denominator, which is 63. (8/9) * (7/7) - (2/7) * (9/9) = 56/63 - 18/63 = 38/63

So, the results of these calculations are:

1. 2/3 + 1/5 = 13/15
2. 3/4 + 1/10 = 17/20
3. 5/8 + 3/10 = 37/40
4. 2/7 + 1/3 = 13/21
5. 1/6 + 1/8 = 7/24
6. 5/8 - 1/3 = 7/24
7. 2/3 - 3/10 = 11/30
8. 11/12 - 3/8 = 13/24
9. 3/4 - 2/7 = 13/28
10. 1/2 + 1/7 = 9/14
11. 2/9 + 3/7 = 41/63
12. 8/9 - 2/7 = 38/63
