Suppose the fraction is

y

x

If 1 is added to the numerator and 1 is subtracted to the denominator the fraction becomes 1

y−1

x+1

=1

x+1=y−1

x−y=−2 Equation (1)

If 1 is added to the denominator the fraction becomes half

y+1

x

=

2

1

2x=y+1

2x−y=1 Equation (2)

On subtracting Equation 1 from 2 we get

2x−y−x+y=1+2

x=3

Substituting the value of x in equation 1 we get,

3−y=−2

y=5
