Question

-17/30 - 11/-15 - 7/12

nhanh nhé mk tk cho

Answer 1

\(\frac{-17}{30}-\frac{11}{-15}-\frac{7}{12}\)

\(=\frac{-34}{60}+\frac{44}{60}-\frac{35}{60}\)

\(=\frac{-34+44-35}{60}\)

\(=\frac{-45}{60}=\frac{-3}{4}\)

Answer 2

-5/12 nhé

Answer 3

\(\frac{-17}{30}-\frac{11}{-15}-\frac{7}{12}=\frac{\left(-17\right).2}{60}-\frac{\left(-11\right).4}{60}-\frac{7.5}{60}\)

                                             \(=\frac{-34-\left(-44\right)-35}{60}=\frac{-25}{60}=\frac{-5}{12}\)

Answer 4

\(\frac{-17}{30}\)_\(\frac{11}{-15}\)_\(\frac{7}{12}\)

=\(\frac{-34}{60}\)_\(\frac{-44}{60}\)_\(\frac{35}{60}\)

=\(\frac{\left(-34\right)-\left(-44\right)-35}{60}\)

=\(\frac{-5}{12}\)
