The first step is to ignore potassium altogether and isolate the phosphate anion.
Phosphate has a total charge of -3. Assume that the oxygens each have an oxidation number of -2. Add those up to get -8. Then subtract (-8) - (-3) = +5.
So phosphorous has an oxidation state of +5.
This process will work for all oxygen containing anions except peroxide and superoxide.

What is the oxidation number of one chromium atom in potassium dichromate?
Potassium dichroamte is K2Cr2O7, in the dichroamte ion both Cr atoms have an oxidation number of +6.
What is the oxidation number of K3PO4?
The oxidation number of what in K3PO4? In that compound the oxidation number of oxygen is -2, the oxidation number of potassium is +1, and the oxidation number of phosphorus is +5.Realistically, in most compounds you can generally take it as a given that the oxidation number of oxygen is -2 and the oxidation number of any alkali metal is +1. In potassium phosphate, that only leaves the oxidation number of phosphorus to figure out, and since they have to come out to a total of zero ...The oxidation number of a compound is essentially a meaningless phrase.

+6
Determine the oxidation number os Se in K2SeO4?
The oxidation number of oxygen is 2- and the oxidation number of potassium is 1+. Seeing as the molecule is neutral we can easily work out that the oxidation number of Se as 6+. (-8 + 2 = +6)
