$ Assume the faction number is $ \frac{x}{x+1} \\ $ ATQ $\\\\ \frac{x+3}{x+4} = \frac{3}{28}\\\\ 28(x+3) = 3(x+4) \\ 28x + 84 = 3x + 12 \\ 25 x = -72 \\ x = \frac{-72}{25} \\ $ Fraction number is $ = \frac{\frac{-72}{25}}{1+\frac{-72}{25}} \\ = \frac{\frac{-72}{25}}{\frac{-47}{25}} \\ = \frac{72}{47}
