Решите задачу:

$(1 \frac{4}{9}+1 \frac{1}{6})*1 \frac{4}{5}-3 \frac{1}{9}:2 \frac{1}{3}=( \frac{13}{9}+ \frac{7}{6})* \frac{9}{5}- \frac{28}{9}: \frac{7}{3}=( \frac{26}{18}+ \frac{21}{18})* \frac{9}{5}- \frac{28*3}{9*7}$
$\frac{47}{18}* \frac{9}{5}- \frac{4}{3}= \frac{47}{10}- \frac{4}{3}= \frac{141}{30}- \frac{40}{30}= \frac{101}{30}=3 \frac{11}{30}$
