e: \(=\left(\dfrac{3}{17}+\dfrac{14}{17}\right)+\left(-\dfrac{5}{13}-\dfrac{8}{13}\right)-\dfrac{18}{35}-\dfrac{17}{35}=-1\)
f: \(=\left(-\dfrac{3}{8}-\dfrac{5}{8}\right)+\left(\dfrac{12}{25}+\dfrac{13}{25}\right)-\dfrac{2}{5}=-\dfrac{2}{5}\)
g: \(=\dfrac{9}{16}+\dfrac{7}{16}+\dfrac{-8}{27}-\dfrac{19}{27}+1=1\)
