EXPLANATION.
Let the numerator of a fraction = x
Let the denominator of fraction = 3x - 1
To find the fraction.
According to the question,
adding 3 to the numerator and
denominator gives = 1/2
=> x + 3 / 3x - 1 + 3 = 1/2
=> x + 3 / 3x + 2 = 1/2
=> 2 ( x + 3 ) = 3x + 2
=> 2x + 6 = 3x + 2
=> 4 = x
Therefore,
Numerator = 4
Denominator = 3(4) - 1 = 11
Fraction = 4/11
