Explicación paso a paso:

$-1-(\frac{1}{3} + (\frac{2}{3}- (\frac{1}{5} +\frac{1}{8})-(\frac{1}{4}-\frac{1}{5})))=\\\\-1 -(\frac{1}{3} + (\frac{2}{3}- (\frac{8+5}{40})-(\frac{5-4}{20})))=\\\\-1- (\frac{1}{3} + (\frac{2}{3}- \frac{13}{40} - \frac{1}{20}))=\\\\-1- (\frac{1}{3} + (\frac{2}{3}- \frac{13-2}{40}))=\\\\-1-(\frac{1}{3} + (\frac{2}{3}- \frac{11}{40}))=\\\\-1 - (\frac{1}{3} + (\frac{80-33}{120})=\\\\-1- (\frac{1}{3}+ \frac{47}{120})=\\\\-1- (\frac{40+47}{120})=\\\\-1- \frac{87}{120}= \\\\-1 -\frac{29}{4}$$-\frac{25}{4}$
