$\frac{ \\ 5x {}^{4} {y}^{3} }{x + 3} i10 {x}^{2} {y}^{3}$
​

Answer 1

$\displaystyle\bf\\\frac{5x^{4} y^{3} }{x+3}:10x^{2} y^{3} =\frac{5x^{4} y^{3} }{x+3}\cdot \frac{1}{10x^{2} y^{3} } =\frac{5\cdot x^{2} \cdot x^{2} \cdot y^{3} }{x+3}\cdot \frac{1}{5\cdot 2\cdot x^{2} \cdot y^{3} } =\\\\\\=\frac{x^{2} }{2\cdot(x+3)} =\frac{x^{2} }{2x+6}$
