\(\left(\frac{3}{8}+-\frac{3}{4}+\frac{7}{12}\right):\frac{5}{6}+\frac{1}{2}\)
\(=\left(\frac{9}{24}+-\frac{18}{24}+\frac{14}{24}\right):\frac{5}{6}+\frac{1}{2}\)
\(=\frac{5}{24}:\frac{5}{6}+\frac{1}{2}\)
\(=\frac{5}{24}.\frac{6}{5}+\frac{1}{2}\)
\(=\frac{1}{4}+\frac{1}{2}\)
\(=\frac{1}{4}+\frac{2}{4}\)
\(=\frac{3}{4}\)
\(\frac{1}{2}+\frac{3}{4}-\left(\frac{3}{4}-\frac{4}{5}\right)\)
\(=\frac{1}{2}+\frac{3}{4}-\left(\frac{15}{20}-\frac{16}{20}\right)\)
\(=\frac{1}{2}+\frac{3}{4}-\frac{-1}{20}\)
\(=\frac{10}{20}+\frac{15}{20}-\frac{-1}{20}\)
\(=\frac{25}{20}-\frac{-1}{20}\)
\(=\frac{26}{20}\)
\(=\frac{13}{10}\)

\(4\frac{5}{6}+\frac{1}{6}.\left(8-2\frac{2}{3}\right)\)
\(=\frac{29}{6}+\frac{1}{6}.\left(8-\frac{8}{3}\right)\)
\(=\frac{29}{6}+\frac{1}{6}.\left(\frac{24}{3}-\frac{8}{3}\right)\)
\(=\frac{29}{6}+\frac{1}{6}.\frac{16}{3}\)
\(=\frac{29}{6}+\frac{8}{9}\)
=\(=\frac{103}{18}\)
\(4\frac{5}{6}+\frac{1}{6}.\left(8-2\frac{2}{3}\right)\)
\(=\frac{29}{6}+\frac{1}{6}.\left(8-\frac{8}{3}\right)\)
\(=\frac{29}{6}+\frac{1}{6}.\left(\frac{24}{3}-\frac{8}{3}\right)\)
\(=\frac{29}{6}+\frac{1}{6}.\frac{16}{3}\)
\(=\frac{29}{6}+\frac{8}{9}\)
\(=\frac{87}{18}+\frac{16}{18}\)
\(=\frac{103}{18}\)
