( ((5),(5) )/ (((25)),(5) )) = (1/((25×24×23×22×21)/(5×4×3×2×1)))   = (1/(5×23×22×21)) = (1/(53130))

$$\frac{\begin{pmatrix}{\mathrm{5}}\\{\mathrm{5}}\end{pmatrix}}{\begin{pmatrix}{\mathrm{25}}\\{\mathrm{5}}\end{pmatrix}}\:=\:\frac{\mathrm{1}}{\frac{\mathrm{25}×\mathrm{24}×\mathrm{23}×\mathrm{22}×\mathrm{21}}{\mathrm{5}×\mathrm{4}×\mathrm{3}×\mathrm{2}×\mathrm{1}}}\: \\ $$$$=\:\frac{\mathrm{1}}{\mathrm{5}×\mathrm{23}×\mathrm{22}×\mathrm{21}}\:=\:\frac{\mathrm{1}}{\mathrm{53130}} \\ $$
