\(\left(x+\frac{1}{2}\right):\frac{1}{1+\frac{1}{2}}=\frac{1}{1+\frac{1}{2}}\)
\(\left(x+\frac{1}{2}\right):\frac{1}{\frac{3}{2}}=\frac{1}{\frac{3}{2}}\)
\(x+\frac{1}{2}=\frac{2}{3}.\frac{2}{3}=\frac{4}{9}\)
\(x=\frac{4}{9}-\frac{1}{2}=-\frac{1}{18}\)

\(\left(x+\frac{1}{2}\right):\frac{2}{3}=\frac{2}{3}\)
\(x+\frac{1}{2}=\frac{2}{3}.\frac{2}{3}\)
\(x+\frac{1}{2}=\frac{4}{9}\)
\(x==\frac{4}{9}-\frac{1}{2}\)
\(x=\frac{4}{9}-\frac{1}{2}\)
