v/v calculation by: Anonymous

I followed the formula for v/v problems in my pharmacy technician text book. The formula is follows:

active ingredient divided by the total ingredient, which is the total of the active and base. In this problem the total ingredient is 260, so the equation would be:

200/60 = 3.33%

Would someone please confirm this or let know what the solution would be?
