The smaller triangle is also a 3-4-5 triangle, meaning the bigger triangle must be aswell. Since 16 is the '4' part here, you can divide it by 4, get 4, then multiply that 4 by 3, since AC is the '3' part here.

No idea if that explanation makes sense, but atleast in this specific case, it works

How do I know where what my denominators and numerators are when comparing similar triangles ???
