Question

\(\frac{4}{5}+\left(x:\frac{2}{3}-\frac{1}{2}\right)=\frac{9}{10}\)

Answer 1

\(\frac{4}{5}+\left(x:\frac{2}{3}-\frac{1}{2}\right)=\frac{9}{10}\)

\(x:\frac{2}{3}-\frac{1}{2}=\frac{9}{10}-\frac{4}{5}\)

\(x:\frac{2}{3}-\frac{1}{2}=\frac{1}{10}\)

\(x:\frac{2}{3}=\frac{1}{10}-\frac{1}{2}\)

\(x:\frac{2}{3}=\frac{-2}{5}\)

\(x=\frac{-2}{5}X\frac{2}{3}\)

\(x=\frac{-4}{15}\)

Answer 2

\(\frac{4}{5}+\left(x:\frac{2}{3}-\frac{1}{2}\right)=\frac{9}{10}\)

\(x:\frac{2}{3}-\frac{1}{2}=\frac{1}{10}\)

\(x:\frac{2}{3}=\frac{3}{5}\)

\(x=\frac{2}{5}\)
