EXPLANATION.
The numerator of a fraction is 2 less than the
denominator.
Let the numerator of the fraction = ( x - 2 )
Let the denominator of the fraction = x
fraction become = x - 2 / x
if 1 is added to it's denominator, it becomes
1/2.
=> x - 2 / x + 1 = 1/2
=> 2 ( x - 2 ) = x + 1
=> 2x - 4 = x + 1
=> x = 5
Therefore,
Numerator = x - 2 = 5 - 2 = 3
Denominator = x = 5
Fraction = 3/5
