\(-\left(\frac{-5}{4}\right) +\left(\frac{-10}{-5}\right) +\left(\frac{8}{-3}\right)\)

\(-\left(\frac{-5}{4}\right) +\left(\frac{-10}{-5}\right) +\left(\frac{8}{-3}\right)\\= \frac{5}{4}+ \frac{10}{5}-\frac{8}{3}\\=\frac{5}{4}+\frac{2}{1}-\frac{8}{3}\\=\frac{15}{12}+\frac{24}{12}-\frac{32}{12}\\=\frac{15+24-32}{12}\\=\frac{7}{12}\)
