1864.3. Main feature of fraction

Write the correct answer!

Change the fraction so that it is possible to shorten it by using main feature of fraction! Example:
\frac{x^2y+y^3+5x^2+xy}{zy+5z}=\frac{\left(x^2+y^2\right)\left(y+5\right)}{zy+5z}=\frac{\left(x^2+y^2\right)\left(y+5\right)}{z\left(y+5\right)}
\frac{2y+6}{zy+3z+5y+15}
