Bereken

\(-\left(\frac{10}{9}\right) +\left(\frac{-10}{-6}\right) -\left(\frac{-8}{-2}\right)\)

\(-\left(\frac{10}{9}\right) +\left(\frac{-10}{-6}\right) -\left(\frac{-8}{-2}\right)\\= \frac{-10}{9}+ \frac{10}{6}-\frac{8}{2}\\=\frac{-10}{9}+\frac{5}{3}-\frac{4}{1}\\=\frac{-10+5-4}{9}\\=\frac{-9}{9}\\=\frac{-1}{1}\)
