I am not sure you wanted this but I try...

Explanation:

Consider a product that casts #100#; a #15%# discount means that you pay for it #100-15=85# that is less or you can say that its price was reduced.
Same thing with, say, a temperature; if an object change temperature from #100# to #85# we say that the temperature decreases of #15# or #15%#.

I think that the important thing is the word "discount" that can be thought as similar to reduction; the percentage represents the fraction of 100 that represents this reduction.
