I can help solve the exercises from the image you provided. The image shows a set of fractional and arithmetic operations labeled 1 to 18. I'll start solving them step by step. Here are the operations from 1 to 18:

1. \( \frac{2}{5} + \frac{2}{5} \)
2. \( \frac{8}{6} - \frac{6}{5} \)
3. \( \frac{9}{5} + \frac{5}{2} \)
4. \( \frac{1}{7} - \frac{1}{8} \)
5. \( \frac{-2}{8} \times \frac{-3}{5} \)
6. \( \frac{-4}{7} + \frac{1}{7} \)
7. \( \frac{2}{3} \times \frac{9}{8} \)
8. \( \frac{10}{12} \div \frac{-5}{11} \)
9. \( \frac{6}{5} \times \frac{1}{3} \)
10. \( \frac{3}{10} + \frac{2}{4} \)
11. \( \frac{5}{8} + \frac{-4}{3} \)
12. \( \frac{-3}{2} - \frac{1}{10} \)
13. \( \frac{1}{6} + \frac{2}{9} \)
14. \( \frac{4}{3} + \frac{8}{8} \)
15. \( \frac{6}{7} + \frac{1}{5} \)
16. \( \frac{7}{4} \div \frac{2}{9} \)
17. \( \frac{1}{2} + \frac{5}{6} \)
18. \( \frac{3}{9} + \frac{2}{9} \)

Would you like me to solve all of these, or a specific selection from the list? Let me know!
