Answer 1

31/17+(-5/13)+(-8/13)-14/17

=(31/17-14/17)+[-5/13+(-8/13)]

=1+(-1)

=0

Answer 2

\(\frac{31}{17}+\frac{-5}{13}+\frac{-8}{13}-\frac{14}{17}\)

\(=\left[\frac{31}{17}-\frac{14}{17}\right]+\left[\frac{-5}{13}+\frac{-8}{13}\right]\)

\(=1+(-1)=0\)

Answer 3

\(\frac{31}{17}+\frac{-5}{13}+\frac{-8}{13}-\frac{14}{17}\)

\(=\left(\frac{31}{17}-\frac{14}{17}\right)+\left(\frac{-5}{13}+\frac{-8}{13}\right)\)

\(=1+\left(-1\right)\)

\(=0\)
