$[( \frac{-1}{2} - \frac{1}{3} )².( \frac{1}{} + \frac{1}{5} )] : [ \frac{-3}{5} . ( \frac{-2}{} + \frac{1}{3} )²]$

$[( \frac{-3-2}{6} )².( \frac{5+1}{5} )]:[ \frac{-3}{5} .( \frac{-6+1}{3} )²]$

$[( \frac{-5}{6})².( \frac{6}{5} ]:[ \frac{-3}{5} .( \frac{-5}{3} )²]$

$[ \frac{25}{6} . \frac{6}{5} ]:[ \frac{-3}{5} . \frac{25}{9}] =$

$\frac{150}{30} : \frac{-75}{45} =$

$\frac{150}{30} . \frac{-45}{75} =$

cancela, fica mais fácil

$\frac{5}{} . \frac{-3}{5} =-3$
