(-9÷4×5÷3)-(-13÷2×6÷-169)

= ( -9/4 * 5/3 ) - ( -13/2 * 6/-169 )

= ( -95/43 ) - ( 136 / 2169 )

= ( - 15/4) - (3/13)

= -207/52

(\frac{3}{11} \times \frac{5}{6}) - (\frac{9}{12} \times \frac{4}{3}) + (\frac{5}{13} \times \frac{6}{15})

Re-arrange suitably and find the sum in each of the following :

(i) $\frac{11}{12} + \frac{- 17}{3} + \frac{11}{2} + \frac{- 25}{2}$

(ii) $\frac{- 6}{7} + \frac{- 5}{6} + \frac{- 4}{9} + \frac{- 15}{7}$

(iii) $\frac{3}{5} + \frac{7}{3} + \frac{9}{5} + \frac{- 13}{15} + \frac{- 7}{3}$

(iv) $\frac{4}{13} + \frac{- 5}{8} + \frac{- 8}{13} + \frac{9}{13}$

(v) $\frac{2}{3} + \frac{- 4}{5} + \frac{1}{3} + \frac{2}{5}$

(vi) $\frac{1}{8} + \frac{5}{12} + \frac{2}{7} + \frac{7}{12} + \frac{9}{7} + \frac{- 5}{16}$

(\begin{matrix} \frac{- 9}{13} \times \frac{5}{6} \end{matrix}) - (\begin{matrix} \frac{- 9}{13} \times \frac{4}{6} \end{matrix}) = \frac{- 9}{13} \times (\begin{matrix} \frac{5}{6} - \frac{4}{6} \end{matrix})
