Question

\(\dfrac{-5}{21}\)+\(\dfrac{-2}{21}\)+\(\dfrac{8}{24}\)

Answer 1

\(\dfrac{-5}{21}+\dfrac{-2}{21}+\dfrac{8}{24}=\dfrac{\left(-5\right)+\left(-2\right)}{21}+\dfrac{1}{3}\)

=\(\dfrac{-7}{21}+\dfrac{1}{3}\)=\(\dfrac{-1}{3}+\dfrac{1}{3}=0\).

Answer 2

= \(\dfrac{-5+\left(-2\right)}{21}\) + \(\dfrac{8}{24}\)

= \(\dfrac{-1}{3}\) + \(\dfrac{1}{3}\)

= 0

Answer 3

\(\dfrac{-5}{21}\)+\(\dfrac{-2}{21}\)+\(\dfrac{8}{24}\)

=\(\dfrac{\left(-5\right)+\left(-2\right)}{21}\)+\(\dfrac{1}{3}\)

=\(\dfrac{-1}{3}\)+\(\dfrac{1}{3}\)

=0

Answer 4

=\(\dfrac{-1}{3}+\dfrac{1}{3}=0\)

Answer 5

=\(\dfrac{-5}{21}+\dfrac{-2}{21}+\dfrac{1}{3}\)

=\(\dfrac{-7}{21}+\dfrac{1}{3}\)

=\(\dfrac{-1}{3}+\dfrac{1}{3}\)

=0

Answer 6

\(\dfrac{-5}{21}\) + \(\dfrac{-2}{21}\) + \(\dfrac{8}{24}\) =
