\(\left(\dfrac{1}{3}-\dfrac{1}{5}\right).75\%-\left(\dfrac{1}{34}+\dfrac{2}{9}\right)+\left(\dfrac{9}{17}-\dfrac{-11}{9}\right)\)
\(=\left(\dfrac{1}{3}-\dfrac{1}{5}\right).\dfrac{3}{4}-\left(\dfrac{1}{34}+\dfrac{2}{9}\right)+\left(\dfrac{9}{17}+\dfrac{11}{9}\right)\)
\(=\dfrac{2}{15}.\dfrac{3}{4}-\dfrac{77}{306}+\dfrac{268}{153}\)
\(=\dfrac{1}{10}-\dfrac{613}{306}\)
\(=-\dfrac{1456}{765}\)
