Вычислите значение выражения:
$0,9 * (1\frac{5}{9} - \frac{4}{9} : (\frac{5}{8} + \frac{3}{8} : 3))$.
$0,9 * (1\frac{5}{9} - \frac{4}{9} : (\frac{5}{8} + \frac{3}{8} : 3)) = \frac{9}{10} * (1\frac{5}{9} - \frac{4}{9} : (\frac{5}{8} + \frac{3}{8} * \frac{1}{3})) = \frac{9}{10} * (1\frac{5}{9} - \frac{4}{9} : (\frac{5}{8} + \frac{1}{8})) = \frac{9}{10} * (1\frac{5}{9} - \frac{4}{9} : \frac{3}{4}) = \frac{9}{10} * (1\frac{5}{9} - \frac{4}{9} * \frac{4}{3}) = \frac{9}{10} * (1\frac{5}{9} - \frac{16}{27}) = \frac{9}{10} * (\frac{42}{27} - \frac{16}{27}) = \frac{9}{10} * \frac{26}{27} = \frac{1}{5} * \frac{13}{3} = \frac{13}{15}$
