c: \(=\left(-1+\dfrac{9}{23}+\dfrac{1}{3}\right)+\dfrac{-9}{23}-\dfrac{1}{3}\)
\(=-1+\dfrac{9}{23}-\dfrac{9}{23}+\dfrac{1}{3}-\dfrac{1}{3}=-1\)
d: \(=\dfrac{3}{3}\cdot\dfrac{-28}{28}\cdot\dfrac{7}{11}\cdot22=-22\cdot\dfrac{7}{11}=-14\)
g: \(=-\dfrac{3}{7}\left(\dfrac{15}{13}+\dfrac{11}{13}+1\right)=\dfrac{-3}{7}\cdot3=-\dfrac{9}{7}\)
