If we add 1 to the numerator and subtract 1 from the denominator, a fraction reduces to 1. It becomes equal to 1/2 if we add 1 only to the denominator. What is the fraction?

  • 1

Let the fraction be x/y. The conditions form (x+1)/(y-1) = 1 and x/(y+1) = 1/2, yielding x – y = -2 and 2x – y = 1. Subtracting gives x = 3 and y = 5. The fraction is 3/5.

    1. Let the required fraction be x/y. According to the first condition, (x + 1)/(y – 1) = 1, which cross-multiplies to x – y = -2. According to the second condition, x/(y + 1) = 1/2, which simplifies to 2x – y = 1. Subtracting the first equation from the second eliminates y, giving x = 3. Substituting x = 3 into x – y = -2 yields y = 5. Hence, the fraction is 3/5.
