How do you get a sum of two percentages?
This is more complicated than it first appears. You cannot simply add percentages together - you need to know what they are percentages out of. So if you have x% being a out of b so that x = 100*a/b and y% being c out of d so that y = 100*c/d Then the sum of the percentages is 100*(a+c)/(b+d). The clearest way to see that you cannot simply add up the percentages is, if you get a 50% score in one exam and a 50% score in another, you do NOT get 100% in the two exams combined!
What are the strengths of using percentages?
Since percentages are based on a common denominator of 100, they are easier to add and subtract.
Can you take four percentages divide by four to get an average of the four percentages?
Yes add the 4 percentages together then divide them by 4 to obtain the average percentage
