- (  \frac{2}{3}+ \frac{4}{5}. \frac{1}{3}   ) ÷ ( \frac{7}{5}+ \frac{12}{5}+ \frac{13}{10}   ) =

- ( \frac{2}{3}+ \frac{4}{15}  ) ÷ ( \frac{7}{5}+ \frac{12}{5}+ \frac{13}{10}   ) =

- ( \frac{5.2+1.4}{15} ) ÷ ( \frac{2.7+2.12+1.13}{10} ) =

- ( \frac{14}{15} ) ÷ ( \frac{51}{10} ) =

-  \frac{14}{15} .  \frac{10}{51} =

-  \frac{140}{765} =

-  \frac{28}{53}
