Question

-3/5 + 1/7 + 3/5 + -5/7

Answer 1

\(=\left(-\dfrac{3}{5}+\dfrac{3}{5}\right)+\left(\dfrac{1}{7}+-\dfrac{5}{7}\right)\\ =0+-\dfrac{4}{7}\\ =-\dfrac{4}{7}\)

Answer 2

\(\dfrac{-3}{5}+\dfrac{1}{7}+\dfrac{3}{5}+\dfrac{-5}{7}\)

\(=\left(\dfrac{-3}{5}+\dfrac{3}{5}\right)+\left(\dfrac{1}{7}+\dfrac{-5}{7}\right)\)

\(=0+\dfrac{-4}{7}\)

\(=-\dfrac{4}{7}\)

Answer 3

=(-3/5+3/5)+(1/7-5/7)

=-4/7

Answer 4

- 3/5 + 1/7 + 3/5 + - 5/7

=( - 3/5 + 3/5 ) + ( 1/7 - 5/7 )

=- 4/7.

Answer 5

=(-3/5+3/5)+(1/7-5/7)

=-4/7

Answer 6

= -\(\dfrac{4}{7}\)
