Answer 1

\(x-25\%\times x=\frac{1}{2}\)

\(x-\frac{25}{100}\times x=\frac{1}{2}\)

\(x\times\left(1-\frac{25}{100}\right)=\frac{1}{2}\)

\(x\times\frac{3}{4}=\frac{1}{2}\)

\(x=\frac{1}{2}\div\frac{3}{4}\)

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

Answer 2

X x(1-25%)=1/2

X x 3/4 =1/2

 x         =1/2:3/4

x             =1/2 x4/3

x                 =2/3
