$(\frac{7}{15}+\frac{23}{45})*(1\frac{4}{11}+\frac{5}{22}):(11\frac{5}{18}-7 \frac{1}{9})= (\frac{21}{45}+\frac{23}{45})*(\frac{15}{11}+\frac{5}{22}):(\frac{203}{18}- \frac{64}{9})= \\\\=\frac{44}{45}*(\frac{30}{22}+\frac{5}{22}):(\frac{203}{18}-\frac{128}{18})=\frac{44}{45}*\frac{35}{22}:\frac{75}{18}=\frac{2}{9}*\frac{7}{1}*\frac{18}{75}=\frac{14}{9}*\frac{18}{75}= \\\\=\frac{14}{1}*\frac{2}{75}=\frac{28}{75}$
