----
Let the fraction be a/b
-----
Equations:
(a-1)/b = 1/3
a/(b+3) = 1/3
-------------------------
Rearrange:
3a -3 = b
3a = b + 3
------------------
Rearrange for elimination:
3a - b = 3
3a - b = 3
-------------------
b = 3a-3
-------------------
Answer:: The fraction is a/(3(a-1)) where a is any number except 1.
