Question

C = \(\dfrac{-1}{5}-\left(\dfrac{1}{2}+\dfrac{3}{4}\right)^2:\dfrac{5}{8}\)

Answer 1

C=\(\dfrac{-1}{5}\)-\(\dfrac{1}{4}+\dfrac{9}{16}\):\(\dfrac{5}{8}\)

C=\(-\dfrac{1}{5}-\dfrac{1}{4}+\dfrac{9}{10}\)

C=\(-\dfrac{9}{20}+\dfrac{9}{10}\)

C=\(\dfrac{9}{20}\)

Answer 2

\(C=\dfrac{-1}{5}-\left(\dfrac{1}{2}+\dfrac{3}{4}\right)^2:\dfrac{5}{8}\)

\(C=\dfrac{-1}{5}-\dfrac{5}{4}^2:\dfrac{5}{8}\)

\(C=\dfrac{-1}{5}-\dfrac{25}{16}:\dfrac{5}{8}\)

\(C=\dfrac{-1}{5}-\dfrac{5}{2}\)

\(C=\dfrac{-27}{10}\)
