Question

\(B=\frac{-2}{3}+\frac{3}{4}-\frac{-1}{6}+\frac{-2}{5}\)

Answer 1

\(B=-\frac{2}{3}+\frac{3}{4}-\left(-\frac{1}{6}\right)+\left(-\frac{2}{5}\right)\)

\(B=\frac{1}{12}-\left(-\frac{1}{6}\right)+\left(-\frac{2}{5}\right)\)

\(B=\frac{1}{4}+\left(-\frac{2}{5}\right)\)

\(B=-\frac{3}{20}.\)

Chúc bạn học tốt!

Answer 2

\(\frac{-2}{3}+\frac{3}{4}-\frac{-1}{6}+\frac{-2}{5}\)

=>\(\frac{1}{12}\)\(-\frac{-1}{6}+\frac{-2}{5}\)

=> \(\frac{1}{4}\)\(+\frac{-2}{5}\)

=>\(\frac{-3}{20}\)
