\(=\left(\dfrac{3}{5}-\dfrac{1}{3}\right):\dfrac{8}{35}-\dfrac{1}{9}-\dfrac{3}{4}\)
\(=\left(\dfrac{9}{15}-\dfrac{5}{15}\right):\dfrac{8}{35}-\dfrac{1}{9}-\dfrac{3}{4}\)
\(=\dfrac{4}{14}.\dfrac{35}{8}-\dfrac{1}{9}-\dfrac{3}{4}\)
\(=\dfrac{7}{6}-\dfrac{1}{9}-\dfrac{3}{4}\)
\(=\dfrac{63}{54}-\dfrac{6}{54}-\dfrac{3}{4}\)
\(=\dfrac{19}{18}-\dfrac{3}{4}\)
\(=\dfrac{76}{72}-\dfrac{54}{72}\)
\(=\dfrac{11}{36}\)
