1) \( \left( 7 - \frac{1}{5} + \frac{1}{3} \right) - \left( 6 + \frac{9}{5} + \frac{4}{3} \right) \)
2) \( 7 + \left( \frac{7}{12} - \frac{1}{2} \right) - \left( \frac{1}{12} + 5 \right) \)
3) \( \left( \frac{1}{2} - \frac{5}{3} \right) - \left( \frac{7}{3} - \frac{5}{2} \right) \)
4) \( \left( \frac{2}{7} - \frac{9}{4} \right) \left( -\frac{3}{7} - \frac{5}{4} \right) - \left( \frac{2}{9} - \frac{7}{4} \right) \)
5) \( \left( 3 - \frac{4}{3} \right) - \left( \frac{5}{1} - \frac{6}{3} \right) - \left( 6 - \frac{7}{4} + \frac{3}{2} \right) \)
6) \( \left( 6 - \frac{2}{4} + \frac{1}{2} \right) - \left( \frac{5}{3} - \frac{7}{5} \right) - \left( \frac{3}{4} - \frac{9}{7} \right) \)
7) \( \left( \frac{5}{3} - \frac{3}{9} + 9 \right) - \left( 2 + \frac{5}{7} - \frac{2}{3} \right) \left( 8 - \frac{4}{3} - 10 \right) \)
8) \( \left( 8 - \frac{9}{4} - \frac{2}{7} \right) - \left( -\frac{6}{3} - \frac{5}{4} \right) - \left( 3 + \frac{2}{4} - \frac{9}{7} \right) \)
