Explicación paso a paso:
[tex]\left(-\frac{5}{3}\right)\:\left(\frac{2}{4}\right)\:+\:\left(\frac{7}{5}-\:\frac{2}{8}\right)\:-\:\left(\frac{1}{2}\right)^3\\\\-\frac{10}{12}+\frac{7}{5}-\frac{2}{8}-\frac{1}{8}\\\\-\frac{5}{6}+\frac{7}{5}-\frac{2}{8}-\frac{1}{8}\\\\-\frac{5}{6}+\frac{7}{5}-\frac{3}{8}\\\\\frac{100}{120}+\frac{168}{120}+\frac{-45}{120}\\\\=\frac{23}{120}[/tex]
