Question

3/17 + -8/15 +-3/17 + 8/15 + 2018/2019

Answer 1

\(\dfrac{3}{17}+\dfrac{-8}{15}+\dfrac{-3}{17}+\dfrac{8}{15}+\dfrac{2018}{2019}=\left(\dfrac{3}{17}-\dfrac{3}{17}\right)+\left(\dfrac{8}{15}-\dfrac{8}{15}\right)+\dfrac{2018}{2019}=\dfrac{2018}{2019}\)

Answer 2

\(\dfrac{3}{17}+\dfrac{-8}{15}+\dfrac{-3}{17}+\dfrac{8}{15}+\dfrac{2018}{2019}\)

\(=0+0+\dfrac{2018}{2019}\)

\(=\dfrac{2018}{2019}\)

Answer 3

(-3/17+3/17)+(-8/15+8/15)+2018/2019

0+0+2018/2019

=2018/2019
