Answer 1

\(\dfrac{-5}{8}\):\(\dfrac{1}{4}\)-\(\dfrac{3}{16}\).4+\(\dfrac{3}{8}\)

=\(\dfrac{\left(-5\right).4}{8.1}\)-\(\dfrac{3.4}{16}\)+\(\dfrac{3}{8}\)

=\(\dfrac{-5}{2}\)-\(\dfrac{3}{4}\)+\(\dfrac{3}{8}\)

=\(\dfrac{\left(-20\right)-6+3}{8}\)=\(\dfrac{-23}{8}\)

Answer 2

\(\dfrac{-5}{8}:\dfrac{1}{4}-\dfrac{3}{16}.4+\dfrac{3}{8}\)

\(=\dfrac{-5}{8}.4-\dfrac{3}{16}.4+\dfrac{3}{8}\)

\(=\dfrac{-10}{16}.4-\dfrac{3}{16}.4+\dfrac{3}{8}\)

\(=\left(\dfrac{-10-3}{16}\right).4+\dfrac{3}{8}\)

\(=\dfrac{-13}{16}.4+\dfrac{3}{8}\)

\(=-\dfrac{13}{4}+\dfrac{3}{8}\)

\(=-\dfrac{26}{8}+\dfrac{3}{8}\)

\(=\dfrac{-26+3}{8}\)

\(=\dfrac{-23}{8}\)
