\(\cfrac{3\sqrt{20}+2\sqrt{28}+\sqrt{12}}{5\sqrt{45}+2\sqrt{175}+\sqrt{75}}\)
\(=\cfrac{3\sqrt{4\times 5}+2\sqrt{4\times 7}+\sqrt{4\times 3}}{5\sqrt{9\times 5}+2\sqrt{25\times7}+\sqrt{25\times 3}}\)
\(=\cfrac{3\times2\sqrt{5}+2\times2\sqrt{7}+2\sqrt{3}}{5\times3\sqrt{5}+2\times5\sqrt{7}+5\sqrt{3}}\)
\(=\cfrac{2[3\sqrt{5}+2\sqrt{7}+\sqrt{3}]}{5[3\sqrt{5}+2\sqrt{7}+\sqrt{3}]}\)
\(=\cfrac{2}{5}\) [Answer]
