\(\frac{4}{9}\cdot\frac{11}{15}+\frac{4}{9}\cdot\frac{4}{15}\)
\(=\frac{4}{9}\left(\frac{11}{15}+\frac{4}{15}\right)\)
\(=\frac{4}{9}\cdot1=\frac{4}{9}\)
\(\left(x-\frac{2}{3}\right).\frac{1}{6}=\frac{1}{8}\)
\(\left(x-\frac{2}{3}\right)=\frac{3}{4}\)
\(x=\frac{17}{12}\)
\(\left(x-\frac{2}{3}\right)\cdot\frac{1}{6}=18\)
\(\Rightarrow x-\frac{2}{3}=18:\frac{1}{6}=108\)
\(\Rightarrow x=108+\frac{2}{3}=\frac{326}{3}\)
\(\Rightarrow x=\frac{326}{3}\)
\(\frac{1}{3}+\frac{2}{3}\cdot x=\frac{2}{5}\)
\(\Rightarrow\frac{2}{3}\cdot x=\frac{2}{5}-\frac{1}{3}=\frac{1}{15}\)
\(\Rightarrow x=\frac{1}{15}:\frac{2}{3}=\frac{1}{10}\)
\(\Rightarrow x=0,1\)
