851:315=X:2412 what is the X?

$$$$\frac{851}{315}=\frac{X}{2412}$$\\
Multiply both sides by 2412 $$\frac{2412*851}{315}=X$$\\$$

$${\mathtt{X}} = {\frac{{\mathtt{2\,412}}{\mathtt{\,\times\,}}{\mathtt{851}}}{{\mathtt{315}}}} \Rightarrow {\mathtt{X}} = {\mathtt{6\,516.228\: \!571\: \!428\: \!571\: \!428\: \!6}}$$

X ≈ 6516
