Answer:
let 'x' be the numerator and 'y' be the denominator
according to the question,
x=y-2 --------eq (1)
x+1/y+1 =3/4
y-2+1/y+1 = 3/4 [from eq (1) x=y-2]
y-1/y+1 = 3/4
4[y-1] = 3[y+1]
4y-4 = 3y+3
4y-3y-4-3=0
y-7=0
y=7
we know that x=y-2
therefore, x=7-2= 5
the original number is 5/7
hope this helps
