$$\frac{11}{2} - \frac{2}{5} \left(\frac{5}{6} + 7 + \frac{7}{4}\right) = \frac{5}{3} = 1.\overline{6}$$

$$\begin{aligned}\frac{11}{2} - \frac{2}{5} \left(\frac{5}{6} + 7 + \frac{7}{4}\right)&=\frac{11}{2} - \frac{2}{5} \left(\frac{5}{6} + \frac{35}{4}\right)\\&=\frac{11}{2} - \frac{2}{5} \cdot \frac{115}{12}\\&=\frac{11}{2} - \frac{23}{6}\\&=\frac{5}{3}\end{aligned}$$
