Answer 2

$\frac{3}{2} \times \frac{5}{4} - \frac{8}{5} + 3 \frac{5}{2} = \\ \frac{3}{2} \times \frac{5}{4} - \frac{8}{5} + \frac{11}{2} = \\ \frac{15}{8} - \frac{8}{5} + \frac{11}{2} = \\ \frac{75}{40} - \frac{64}{40} + \frac{110}{40} = \\ \frac{75 - 64 + 110}{40} = \\ \frac{121}{40}$

$\frac{7}{12} + \frac{5}{10} - 8 \frac{5}{3} + \frac{3}{6} = \\ \frac{7}{12} + \frac{1}{2} - \frac{29}{3} + \frac{1}{2} = \\ \frac{7}{12} + \frac{6}{12} - \frac{116}{12} + \frac{6}{12} = \\ \frac{7 + 6 - 116 + 6}{12} = \\ - \frac{97}{12}$
