Question

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

Answer 1

Answer:

....your ans is 3/5...........

Answer 2

Fraction = 3/5

Step-by-step explanation:

Let x be the numerator and y the denominator.

Given:

(x + 1) / (y - 1) = 1

x - y = -2 -------------(1)

x / (y+1) = 1/2  

2x - y = 1 -------------(2)

Subtracting (2) from (1), we get: -x = -3

Therefore x = +3

Substituting in x = 3 equation 1, we get 3 - y = -2

Therefore y = 5

Hence solved. x = 3, y = 5

So the fraction will be x/y = 3/5.
