Bereken

\(+\left(\frac{-6}{5}\right) -\left(\frac{-8}{-7}\right) -\left(\frac{-10}{-7}\right)\)

\(+\left(\frac{-6}{5}\right) -\left(\frac{-8}{-7}\right) -\left(\frac{-10}{-7}\right)\\= \frac{-6}{5}- \frac{8}{7}-\frac{10}{7}\\=\frac{-42}{35}-\frac{40}{35}-\frac{50}{35}\\=\frac{-42-40-50}{35}\\=\frac{-132}{35}\)
