а)\frac{2}{9}+\frac{3}{6}-\frac{1}{6}=\frac{13}{18}-\frac{1}{6}=\frac{5}{9}

б)8\frac{25}{27}-\left(3\frac{8}{27}+2\frac{3}{9}\right)=8\frac{25}{27}-5\frac{17}{27}=3\frac{8}{27}=3\frac{8}{27}

в)8\frac{3}{17}+\left(7\frac{5}{34}+\frac{9}{34}\right)=8\frac{3}{17}+7\frac{7}{17}=15\frac{10}{17}=15\frac{10}{17} (с плюсом перед скобкой)

в)8\frac{3}{17}-\left(7\frac{5}{34}+\frac{9}{34}\right)=8\frac{3}{17}-7\frac{7}{17}=\frac{13}{17} (с минусом перед скобкой )
