Answer:
![\frac{3}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7D)
Step-by-step explanation:
let x be the value of the denominator , then fraction is
![\frac{x-4}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-4%7D%7Bx%7D)
adding 1 to numerator and denominator , gives
= ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
=
( cross- multiply )
2(x - 3) = x + 1
2x - 6 = x + 1 ( subtract x from both sides )
x - 6 = 1 ( add 6 to both sides )
x = 7
then original fraction
=
= ![\frac{3}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7D)
