Answer 1

Veja uma das formas de resolver.
$-\frac{1}{5}- \left( \frac{2}{3}-1\right)-\frac{1}{3}- \left( \frac{3}{5}+1\right)\\ \\=-\frac{1}{5}- \left( \frac{2}{3}-\frac{3}{3}\right)-\frac{1}{3}- \left( \frac{3}{5}+\frac{5}{5}\right)\\ \\=-\frac{1}{5}- \left( \frac{2-3}{3}\right)-\frac{1}{3}- \left( \frac{3+5}{5}\right)\\ \\=-\frac{1}{5}- \left(- \frac{1}{3}\right)-\frac{1}{3}-\frac{8}{5}\\ \\=-\frac{1}{5}+ \frac{1}{3}-\frac{1}{3}-\frac{8}{5}\\ \\=-\frac{1}{5}-\frac{8}{5}\\ \\=\frac{-1-8}{5}\\ \\=-\frac{9}{5}$
