⠀⠀⠀⠀

Let the denominator be x

⠀⠀⠀⠀

Therefore numerator is x - 4

⠀⠀⠀⠀

Acc. to the question :-

⠀⠀⠀⠀

\sf :\implies\:{\dfrac{x-4+1}{x+1} = \dfrac{1}{2}}

⠀⠀⠀⠀

\sf :\implies\:{\dfrac{x- 3}{x+1} = \dfrac{1}{2}}

⠀⠀⠀⠀

\sf :\implies\:{2 ( x - 3 ) = x + 1 }

⠀⠀⠀⠀

\sf :\implies\:{2x - 6 = x + 1 }

⠀⠀⠀⠀

\sf :\implies\:{2x - x = 6 + 1 }

⠀⠀⠀⠀⠀⠀⠀

\sf :\implies\:{x = 7 }

⠀⠀⠀⠀

Putting value of x in the fraction

⠀⠀⠀⠀

Numerator = x - 4 = 7 - 4 = 3

⠀⠀⠀⠀

Denominator = x = 7
