Let me work through and solve some of the problems from the image you uploaded.

First Column

1. $\frac{1}{5} + \frac{3}{5} = \frac{4}{5}$

2. $\frac{4}{13} + \frac{7}{13} = \frac{11}{13}$

3. $\frac{5}{11} + \frac{2}{11} = \frac{7}{11}$

4. $\frac{3}{8} + \frac{2}{8} = \frac{5}{8}$

5. $\frac{6}{14} + \frac{3}{14} = \frac{9}{14}$

Second Column

6. $\frac{5}{7} - \frac{1}{7} = \frac{4}{7}$

7. $\frac{9}{12} - \frac{3}{12} = \frac{6}{12} = \frac{1}{2}$

8. $\frac{6}{8} - \frac{3}{8} = \frac{3}{8}$

9. $\frac{4}{19} - \frac{2}{19} = \frac{2}{19}$

10. $\frac{8}{7} - \frac{3}{7} = \frac{5}{7}$

Would you like me to continue with the third column, or is there a specific question you'd like more details on? Here are some questions for you to consider next:

1. How do you find a common denominator when adding fractions with different denominators?
2. What are the steps to reduce a fraction to its simplest form?
3. Can you explain the method for subtracting fractions?
4. What is the role of the Least Common Denominator (LCD) in fraction operations?
5. How would you approach mixed fraction operations?

Tip: Always simplify your fractions after performing operations for the cleanest result!
