This was already answered, by @BarfBag

$$\frac{18}{15}=\frac{x}{2700}$$ for example

anonymous · Answer

your answer cannot be right, because there is more copper than steel
how this is possible i have no idea
maybe they lose a lot of copper in the process

anonymous · Answer

in any case get the answer via $$x=\frac{2700\times 18}{15}$$
