Question

\(\dfrac{-2}{5}.\dfrac{5}{8}+\dfrac{5}{8}.\dfrac{3}{5}\)

Answer 1

\(\dfrac{-2}{5}.\dfrac{5}{8}+\dfrac{5}{8}\).\(\dfrac{3}{5}\)

=\(\dfrac{5}{8}\left(\dfrac{-2}{5}+\dfrac{3}{5}\right)\)

= \(\dfrac{5}{8}.\left(-1\right)\)

=\(\dfrac{-5}{8}\)

Answer 2

\(\dfrac{-2}{5}.\dfrac{5}{8}+\)\(\dfrac{5}{8}.\dfrac{3}{5}\)

= \(\dfrac{5}{8}.\left(\dfrac{-2}{5}+\dfrac{3}{5}\right)\)

\(=\dfrac{5}{8}.\dfrac{1}{5}\)

\(=\dfrac{5}{40}=\dfrac{1}{8}\)
