$$2\frac{4}{15} - \left(2 - 1\frac{1}{15}\right) : \frac{4}{9} + \frac{2}{3} =$$
$$= 2\frac{4}{15} - \frac{14}{15} : \frac{4}{9} + \frac{2}{3} =$$
$$= 2\frac{4}{15} - \frac{14}{15} \cdot \frac{9}{4} + \frac{2}{3} =$$
$$= 2\frac{4}{15} - \frac{7}{5} \cdot \frac{3}{2} + \frac{2}{3} =$$
$$= 2\frac{4}{15} - \frac{21}{10} + \frac{2}{3} =$$
$$= 2\frac{8}{30} - 2\frac{3}{10} + \frac{2}{3} =$$
$$= 2\frac{8}{30} - 2\frac{9}{30} + \frac{2}{3} =$$
$$= -\frac{1}{30} + \frac{2}{3} =$$
$$= -\frac{1}{30} + \frac{20}{30} = \frac{19}{30}$$
Ответ: $$\frac{19}{30}$$
