\(+\left(\frac{-4}{-3}\right) +\left(\frac{-6}{6}\right) -\left(\frac{7}{2}\right)\)

\(+\left(\frac{-4}{-3}\right) +\left(\frac{-6}{6}\right) -\left(\frac{7}{2}\right)\\= \frac{4}{3}- \frac{6}{6}-\frac{7}{2}\\=\frac{4}{3}-\frac{1}{1}-\frac{7}{2}\\=\frac{8}{6}-\frac{6}{6}-\frac{21}{6}\\=\frac{8-6-21}{6}\\=\frac{-19}{6}\)
