$\ \ 0,333...+\frac{7}{2} -\Big( \frac{2}{3} +2\Big)\\\\=\frac{3}{9} +\frac{7}{2} -\Big( \frac{2}{3} +\frac{6}{3}\Big)\\\\=\frac{3}{9} +\frac{7}{2} -\Big( \frac{2+6}{3}\Big)\\\\=\frac{3}{9} +\frac{7}{2} - \frac{8}{3}\\\\=\frac{6}{18} +\frac{63}{18} - \frac{48}{18}\\\\=\frac{6+63-48}{18}\\\\=\frac{21^{:3}}{18_{:3}}\\\\=\frac{7}{6}$
