I guess it means that average income (or whatever they are measuring) of X = 1/8 x Y. But is it a valid way to say this in English? In Finnish they use this sometimes in the newspapers and so, and I am thinking I need to get over it. But I still hate it.
It's kinda like "X is 8 times less expensive than Y", which I assume means X = 1/8 x X, but to me would make more sense as X = Y - 8Y = -7Y...
