In a fraction, if the numerator is decreased by 1 and
(W) the denominator is increased by 1 , then the resulting fraction is \( \frac{1}{4} \). Instead, if the numerator is increased by 1 and the denominator is decreased by 1 , then the resulting fraction is \( \frac{2}{3} \). Find the difference of the numerator and the denominator of the fraction.
