((\(\frac{5}{-7}+\frac{-5}{-7}+\frac{4}{3}\)

Answer 1

\(\frac{5}{-7}+\frac{-5}{-7}+\frac{4}{3}\)

\(=\frac{-5}{7}+\frac{5}{7}+\frac{4}{3}\)

\(=0+\frac{4}{3}=\frac{4}{3}\)

Ủng hộ mk nha ^_-

Answer 2

5/-7+-5/-7+4/3

= -7/5+5/7/4/3

=-15/21+15/21+28/21

=28/21

=4/3

  

Answer 3

\(\frac{5}{-7}+\frac{-5}{-7}+\frac{4}{3}\)

\(=\frac{-5}{7}+\frac{5}{7}+\frac{4}{3}\)

=\(0+\frac{4}{3}\)

= \(\frac{4}{3}\)
