$$\frac{ 2 { r }^{ 2 } }{ rs } \times \frac{ 5r-5s }{ 2r-4 { r }^{ 2 } }$$
$\frac{5\left(r-s\right)}{s\left(1-2r\right)}$
$$\frac{2r}{s}\times \frac{5r-5s}{2r-4r^{2}}$$
$$\frac{2r\left(5r-5s\right)}{s\left(2r-4r^{2}\right)}$$
$$\frac{2\times 5r\left(r-s\right)}{2rs\left(-2r+1\right)}$$
$$\frac{5\left(r-s\right)}{s\left(-2r+1\right)}$$
$$\frac{5r-5s}{-2rs+s}$$
