Solution to Fractions:

To solve the given fraction problems, we can follow the same approach for each problem. Let's go through each problem step by step:

1. 2/3 + 1/4: To add fractions, we need to find a common denominator. In this case, the common denominator is 12. We can rewrite the fractions as follows: - 2/3 = 8/12 - 1/4 = 3/12 Now, we can add the fractions: - 8/12 + 3/12 = 11/12

2. 4/5 - 3/4: To subtract fractions, we also need a common denominator. In this case, the common denominator is 20. We can rewrite the fractions as follows: - 4/5 = 16/20 - 3/4 = 15/20 Now, we can subtract the fractions: - 16/20 - 15/20 = 1/20

3. 1/2 - 1/3: Again, we need a common denominator to subtract fractions. The common denominator here is 6. We can rewrite the fractions as follows: - 1/2 = 3/6 - 1/3 = 2/6 Now, we can subtract the fractions: - 3/6 - 2/6 = 1/6

4. 5/6 + 3/8: To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 24. We can rewrite the fractions as follows: - 5/6 = 20/24 - 3/8 = 9/24 Now, we can add the fractions: - 20/24 + 9/24 = 29/24

5. 1/2 + 2/5: To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 10. We can rewrite the fractions as follows: - 1/2 = 5/10 - 2/5 = 4/10 Now, we can add the fractions: - 5/10 + 4/10 = 9/10

6. 1/2 - 2/5: To subtract fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 10. We can rewrite the fractions as follows: - 1/2 = 5/10 - 2/5 = 4/10 Now, we can subtract the fractions: - 5/10 - 4/10 = 1/10

7. 1/4 + 1/6: To add fractions, we need a common denominator. In this case, the common denominator is 12. We can rewrite the fractions as follows: - 1/4 = 3/12 - 1/6 = 2/12 Now, we can add the fractions: - 3/12 + 2/12 = 5/12

8. 9/10 - 5/6: To subtract fractions, we need a common denominator. In this case, the common denominator is 30. We can rewrite the fractions as follows: - 9/10 = 27/30 - 5/6 = 25/30 Now, we can subtract the fractions: - 27/30 - 25/30 = 2/30

9. 3/4 + 2/3: To add fractions, we need a common denominator. In this case, the common denominator is 12. We can rewrite the fractions as follows: - 3/4 = 9/12 - 2/3 = 8/12 Now, we can add the fractions: - 9/12 + 8/12 = 17/12

10. 3/5 - 1/3: To subtract fractions, we need a common denominator. In this case, the common denominator is 15. We can rewrite the fractions as follows: - 3/5 = 9/15 - 1/3 = 5/15 Now, we can subtract the fractions: - 9/15 - 5/15 = 4/15

11. 3/4 - 2/3: To subtract fractions, we need a common denominator. In this case, the common denominator is 12. We can rewrite the fractions as follows: - 3/4 = 9/12 - 2/3 = 8/12 Now, we can subtract the fractions: - 9/12 - 8/12 = 1/12

12. 3/4 + 3/14: To add fractions, we need a common denominator. In this case, the common denominator is 28. We can rewrite the fractions as follows: - 3/4 = 21/28 - 3/14 = 6/28 Now, we can add the fractions: - 21/28 + 6/28 = 27/28

13. 1/4 - 1/6: To subtract fractions, we need a common denominator. In this case, the common denominator is 12. We can rewrite the fractions as follows: - 1/4 = 3/12 - 1/6 = 2/12 Now, we can subtract the fractions: - 3/12 - 2/12 = 1/12

14. 3/5 + 1/3: To add fractions, we need a common denominator. In this case, the common denominator is 15. We can rewrite the fractions as follows: - 3/5 = 9/15 - 1/3 = 5/15 Now, we can add the fractions: - 9/15 + 5/15 = 14/15

15. 4/5 + 3/4: To add fractions, we need a common denominator. In this case, the common denominator is 20. We can rewrite the fractions as follows: - 4/5 = 16/20 - 3/4 = 15/20 Now, we can add the fractions: - 16/20 + 15/20 = 31/20

16. 7/10 - 1/4: To subtract fractions, we need a common denominator. In this case, the common denominator is 20. We can rewrite the fractions as follows: - 7/10 = 14/20 - 1/4 = 5/20 Now, we can subtract the fractions: - 14/20 - 5/20 = 9/20

Please note that the solutions provided above are based on the given fractions and the standard rules for adding and subtracting fractions.
