Answer:

let \: the \: no \: be \: x \\  \\ according \: to \: the \: question \\  \\ x -  \frac{1}{2}   \times  \frac{1}{2}  =  \frac{1}{8}   \\  \\ x -  \frac{1}{4}  =  \frac{1}{8}  \\   \\ x =  \frac{1}{8}  +  \frac{1}{4}  \\  \\ x =  \frac{1 + 2}{8}  \\  \\ x =  \frac{3}{8}  \\  \\ lets \: check \\  \\   \frac{3}{8}  -  \frac{1}{2}  \times  \frac{1}{2}  \\  \\  \frac{3}{8}  -  \frac{1}{4}  \\  \\  \frac{3 - 2}{8}  =  \frac{1}{8} \\ so \: the \: answer \: is \: right \\  \\  \\ then \: the \: number \: will \:  \frac{3}{8} answer
