Submerged Objects: Is My Assumption Correct?

[Erathsmus]

Is it wrong for me to assume the following?

If an object is 50% submerged in water, may I say that-
(Average Density of Object)/(Density of Water) *100 = 50

Thank you for reading this, it's just an observation that I would like to know is(or is not) correct.

Yes, assuming that the object is floating that way.
