1. $\frac{7}{2} - \frac{9}{7} = \frac{49}{14} - \frac{18}{14} = \frac{31}{14} = 2\frac{3}{14}$
2. $(-\frac{4}{3}) + (-\frac{6}{7}) = -\frac{28}{21} + -\frac{18}{21} = -\frac{46}{21} = -2\frac{4}{21}$
3. $(-\frac{1}{2}) - (-\frac{6}{5}) = -\frac{5}{10} + \frac{12}{10} = \frac{7}{10}$
4. $\frac{27}{7} \times (-\frac{2}{7}) = -\frac{54}{49} = -1\frac{5}{49}$
5. $\frac{7}{8} \div \frac{10}{9} = \frac{7}{8} \times \frac{9}{10} = \frac{63}{80}$
6. $\frac{20}{7} - \frac{5}{2} = \frac{40}{14} - \frac{35}{14} = \frac{5}{14}$
7. $(-\frac{3}{2}) \div (-\frac{7}{3}) = -\frac{3}{2} \times -\frac{3}{7} = \frac{9}{14}$
8. $\frac{7}{3} \times (-\frac{13}{8}) = -\frac{91}{24} = -3\frac{19}{24}$
9. $(-\frac{7}{6}) \div \frac{16}{5} = -\frac{7}{6} \times \frac{5}{16} = -\frac{35}{96}$
10. $(-\frac{3}{2}) \times \frac{3}{2} = -\frac{9}{4} = -2\frac{1}{4}$
