Solution: Let the fraction be a/b According to the given information, (a+1)/(b-1) = 1 => a – b = -2 ………………………………..(i) a/(b+1) = 1/2 => 2a-b = 1…………………………………(ii) When equation (i) is subtracted from equation (ii) we get, a = 3 …………………………………………………..(iii) When a = 3 is substituted in equation (i) we get, 3 – b = -2 -b = -5 b = 5
