$(3\frac{1}{4} +1\frac{1}{6} :1\frac{5}{9}) :2\frac{2}{7} +5\frac{1}{9} :7\frac{2}{3}= (\frac{13}{4} +\frac{7}{6} :\frac{14}{9}) :\frac{16}{7} +\frac{46}{9} :\frac{23}{3}=(\frac{39}{12} +\frac{14}{12} *\frac{9}{14}) *\frac{7}{16} +\frac{46}{9} *\frac{3}{23}=(\frac{53}{12}*\frac{9}{14}) *\frac{7}{16} +\frac{2}{3} *\frac{1}{1}=(\frac{53}{4}*\frac{3}{14}) *\frac{7}{16} +\frac{2}{3}=\frac{159}{56} *\frac{7}{16} +\frac{2}{3}=\frac{159}{8} *\frac{1}{16} +\frac{2}{3}=\frac{159}{128} +\frac{2}{3}=$

$\frac{477}{384}+\frac{256}{328} =\frac{733}{328} =2\frac{77}{328}$

$2\frac{2}{3}:2+(\frac{4}{15}+\frac{2}{5}):(3\frac{1}{3}*\frac{3}{5})=\frac{8}{3}*\frac{1}{2} +(\frac{4}{15}+\frac{6}{15}):(\frac{10}{3}*\frac{3}{5})=\frac{8}{6}+\frac{10}{15}:\frac{30}{15} =\frac{8}{6}+\frac{10}{15}*\frac{15}{30}=\frac{8}{6}+\frac{2}{1}*\frac{2}{3}=\frac{8}{6}+\frac{4}{3}=\frac{8}{6}+\frac{8}{6}=\frac{16}{6}=\frac{8}{3} =2\frac{2}{3}$
