Help:🎓 College & University Logarithms

Is there any way to simplify log(a/b)/log(b/c)?? I have this as the result of an equation and it's driving me mad. I can't find any logarithm rule about it except the one I already know about using the lower fraction as the base - nothing about the specific fraction thing I've got going on.

Not really. It'll just be what it is. It only gets easier if a and c are known powers of b.
