$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

$( \frac{26}{ - 9} \times - \frac{12}{13} ) - ( \frac{15}{14} \times - \frac{7}{25} )$

$= > ( \frac{2}{9} \times 12) - ( \frac{15}{2} \times - \frac{1}{25} )$

$= > (\frac{2}{3} \times 4) - ( \frac{3}{2} \times - \frac{1}{5})$

$= > \frac{8}{3} - ( - \frac{3}{10}) = \frac{8}{3} + \frac{3}{10}$

$= \frac{80 + 3}{30} = {\bold{\pink{\frac{83}{30} }}}$

Calculation procedure:

1. 26 is cancelled by 13 and 14 is cancelled by 7
2. 12 and 9 is cancelled by 3 & 15 and 25 is cancelled by 5.
3. L.C.M of 3 and 10 is 30.
