\(\left(\dfrac{2}{7}-6-\dfrac{3}{5}\right)-\left(5-\dfrac{3}{5}+\dfrac{1}{7}\right)\)

\(D=-1\dfrac{5}{7}.15+\dfrac{2}{7}.\left(-15\right)+\left(-105\right).\left(\dfrac{2}{3}-\dfrac{4}{5}+\dfrac{1}{7}\right)\)

\(C=\dfrac{3}{14}:\dfrac{1}{28}-\dfrac{13}{21}:\dfrac{1}{28}-\dfrac{29}{42}:\dfrac{1}{28}-8\)

\(\text{c) \dfrac{3}{14} : \dfrac{1}{28} - \dfrac{13}{21} : \dfrac{1}{28} - \dfrac{29}{42} : \dfrac{1}{28} - 8}\)

\(F=\dfrac{-5}{9}.\dfrac{3}{11}+\dfrac{-13}{18}.\dfrac{3}{11}\)

\(A=\left(\dfrac{-40}{51}.0.32.\dfrac{17}{20}\right):\dfrac{64}{75}\)
