Answer 2

Let the denominator be x.

Given that the numerator of a rational number is 4 less than denominator = x - 4.

Therefore the original fraction = x - 4/x  ------- (1)

Now,

if 1 is added to numerator and denominator both, the rational number becomes 1/2.

$= \ \textgreater \ \frac{x - 4 + 1}{x + 1} = \frac{1}{2}$

$= \ \textgreater \ \frac{x - 3}{x + 1} = \frac{1}{2}$

= > 2(x - 3) = x + 1

= > 2x - 6 = x + 1

= > 2x - x = 1 + 6

= > x = 7.


Therefore the original fraction = 7 - 4/7

                                                   = 3/7.



Therefore the rational number = 3/7.



Hope this helps!
