[tex][ \frac{1}{3} + \frac{1}{3} \div ( {}^{3)} 1 - \frac{1}{3} ) ] \div \frac{3}{2} =[ \frac{1}{3} + \frac{1}{3} \div ( \frac{3}{3} - \frac{1}{3}) ] \times \frac{2}{3} = ( \frac{1}{3} + \frac{1}{3} \div \frac{2}{3} ) \times \frac{2}{3} = ( \frac{1}{3} + \frac{1}{\not{3}} \times \frac{\not{3}}{2}) \times \frac{2}{3} \\ [/tex]
[tex] = ( \frac{ {}^{2)} 1}{3} + \frac{ {}^{3)} 1}{2} ) \times \frac{2}{3} = ( \frac{2}{6} + \frac{3}{6} ) \times \frac{2}{3} = \frac{5}{\not{6}} \times \frac{\not{2}}{3} = \frac{5}{3} \times \frac{1}{3} = \boxed{ \frac{5}{9} } \\ [/tex]
