[tex]( \frac{2}{ 1 - \frac{2}{3} } + \frac{ \frac{2}{3} - 1 }{2} ) = \\ = \frac{2}{ \frac{3}{3} - \frac{2}{3} } + \frac{ \frac{2}{3} - \frac{3}{3} }{2} = \\ = \frac{2}{ \frac{1}{2} } - \frac{ \frac{1}{3} }{2} = 5 \frac{5}{6} \\ 5 \frac{5}{6} \div \frac{1}{6} = \frac{35}{6} \times \frac{6}{1} = 35[/tex]
