Bereken

\(-\left(\frac{-2}{3}\right) +\left(\frac{-4}{-8}\right) -\left(\frac{9}{-8}\right)\)

\(-\left(\frac{-2}{3}\right) +\left(\frac{-4}{-8}\right) -\left(\frac{9}{-8}\right)\\= \frac{2}{3}+ \frac{4}{8}+\frac{9}{8}\\=\frac{2}{3}+\frac{1}{2}+\frac{9}{8}\\=\frac{16}{24}+\frac{12}{24}+\frac{27}{24}\\=\frac{16+12+27}{24}\\=\frac{55}{24}\)
