Step-by-step explanation:

Let the denominator of the required fraction be x.

Then, its numerator = (x - 4)

∴ (x - 4) + 1/ x + 1 = 1/2

⇒ x - 3/x + 1 = 1/2

⇒ 2(x - 3) = x + 1

⇒ 2x - 6 = x +1

⇒ 2x - x = 6 + 1

⇒ x = 7.

∴ Denominator = 7 and Numerator = (7 - 4) = 3.

Hence, the required fraction is 3/7.
