Calculate percentage Javascript

Question

I have a question about javascript logic what I use to get percent of two inputs from my text fields  Here is my code       var pPos       pointspossible   val        var pEarned       pointsgiven   val         var perc     pEarned pPos    100  toFixed 3           pointsperc   val perc     For some reason if my inputs are 600 and 200  my result suppose to be  33 333 but I m getting 3 333  If I hard code my values this works fine  If anyone can help I appreciate that  Thanks in advance

You can use this  function percentage partialValue  totalValue       return  100   partialValue    totalValue       Example to calculate the percentage of a course progress base in their activities   const totalActivities   10  const doneActivities   2   percentage doneActivities  totalActivities     Will return 20 that is 20

To get the percentage of a number  we need to multiply the desired percentage percent by that number  In practice we will have   function percentage percent  total        return   percent  100    total  toFixed 2      Example of usage   const percentResult   percentage 10  100      print 10 00    toFixed   is optional for monetary formats
