d)  $\frac{-119}{10}$

Explicación paso a paso:

c)

   $(\frac{13}{7} \div\frac{26}{10}+ \frac{5}{2})* \frac{7}{9} -\frac{3}{7}\\\\~[(\frac{13}{7} *\frac{10}{26})+ \frac{5}{2}]* \frac{7}{9} -\frac{3}{7}\\\\~(\frac{13*10}{7*26}+ \frac{5}{2})* \frac{7}{9} -\frac{3}{7}\\\\~(\frac{130}{182}+ \frac{5}{2})* \frac{7}{9} -\frac{3}{7}\\\\~(\frac{5}{7}+ \frac{5}{2})* \frac{7}{9} -\frac{3}{7}\\\\~(\frac{(2*5)+(7*5)}{14})* \frac{7}{9} -\frac{3}{7}\\\\~\frac{10+35}{14}* \frac{7}{9} -\frac{3}{7}$                                    $~(\frac{45}{14}* \frac{7}{9}) -\frac{3}{7}\\\\\frac{45*7}{14*9}-\frac{3}{7}\\\\\frac{315}{126}-\frac{3}{7}\\\\\frac{5}{2}-\frac{3}{7}\\\\\frac{(7*5)-(2*3)}{14}\\\\\frac{35-6}{14}\\\\\frac{29}{14}$        

d)

 $\frac{9}{5}*(-3)+ \frac{19}{2}\div (\frac{2}{9}- \frac{7}{3})-2\\\\\frac{9*(-3)}{5}+\frac{19}{2}\div\frac{(2*1)-(7*3)}{9}-2\\\\\frac{-27}{5}+\frac{19}{2}\div\frac{2-21}{9}-2\\\\\frac{-27}{5}+\frac{19}{2}\div\frac{-19}{9}-2\\\\\frac{-27}{5}+(\frac{19}{2}*-\frac{9}{19})-2\\\\\frac{-27}{5}+(-\frac{19*9}{2*19})-2$                        $\frac{-27}{5}+(-\frac{171}{38})-2\\\\\frac{-27}{5}+(-\frac{9}{2})-2\\\\\frac{(-27*2)+(-9*5)-(2*10)}{10}\\\\\frac{-54+(-45)-20}{10}\\\\\frac{-119}{10}$
