Question

-3-16/23-2/7-7/23+9/7

Answer 1

=-85/23-2/7-7/23+9/7

=(-2/7+9/7)+(-85/23-7/23)

=1+(-92/23=-4)

=-3

=

Answer 2

\(-3-\dfrac{16}{23}-\dfrac{2}{7}-\dfrac{7}{23}+\dfrac{9}{7}\)

\(=-3-\left(\dfrac{16}{23}+\dfrac{7}{23}\right)-\left(\dfrac{2}{7}-\dfrac{9}{7}\right)\)

\(=-3-\dfrac{23}{23}-\dfrac{-7}{7}\)

\(=-3-1-\left(-1\right)\)

\(=-3-1+1\)

\(=-3\)
