Answer 1

$( \frac{2}{3} - \frac{1}{2}. \frac{4}{15})-( \frac{2}{10} + \frac{3}{5})/( \frac{2}{3} + \frac{4}{9})= \\ \\ ( \frac{3}{2}- \frac{2}{15})-( \frac{1}{5}+ \frac{3}{5} )/( \frac{6+4}{9})= \\ \\ ( \frac{45-4}{30} )-( \frac{4}{5} )/ \frac{10}{9} = \\ \\ \frac{41}{30}- \frac{4}{5} . \frac{9}{10}= \\ \\ \frac{41}{30}- \frac{18}{25} = \\ \\ \frac{205-108}{150} = \\ \\ \frac{97}{150}$
