\(\dfrac{7}{11}+\dfrac{-9}{2}-\dfrac{5}{-3}+1\\ =\dfrac{-85}{22}+\dfrac{5}{3}+1\\ =\dfrac{-145}{66}+1\\ =\dfrac{-79}{66}\)
\(\dfrac{7}{11}+-\dfrac{9}{2}-\dfrac{5}{-3}+1\)
\(=\dfrac{7}{11}-\dfrac{9}{2}+\dfrac{5}{3}+1\)
\(=\dfrac{42}{66}-\dfrac{297}{66}+\dfrac{110}{66}+\dfrac{66}{66}\)
\(=-\dfrac{79}{66}\)
\(\dfrac{7}{11}+\dfrac{-9}{2}-\dfrac{5}{-3}+1\)
\(=\dfrac{7}{11}+\dfrac{-9}{2}-\dfrac{-5}{3}+1\)
\(=\dfrac{14}{22}+\dfrac{-99}{22}-\dfrac{-5}{3}+1\)
\(=\dfrac{-85}{22}-\dfrac{-5}{3}+1\)
\(=\dfrac{-255}{66}-\dfrac{-110}{66}+1\)
\(=\dfrac{-145}{66}+1\)
\(=-\dfrac{79}{66}\)
