Answer 2

$\frac{ - 8}{7} +( \frac{ - 11}{4} ) \\ = - \frac{8}{7} - \frac{11}{4} \\ = \frac{ - 32 - 77}{28} \\ = \frac{ - 109}{28} \\ and \: \frac{1}{9} - ( - \frac{ 12}{13} ) \\ = \frac{1}{9} + \frac{12}{13} \\ = \frac{13 + 108}{108} \\ = \frac{121}{108} \\ now \: - \frac{109}{28} - \frac{121}{108} \\ = \frac{ - 2943 - 847}{756} \\ = \frac{ - 3790}{756}$
