There is a Simple way of finding the percentage. Multiply the obtain marks , score or anything you have scored out of the total scoreboard then multiply the value into 100 and divide the sum of total scoreboard value and as a result the value found will be your percentage. For example there are 4 subject of 100 marks each so sum of total marks = 400 and assume that 1 student got 60 marks each in every 4 subject so in total he obtain 240 marks from sum of total 400 marks. So as a result the Formula will be Obtain marks * 100 / Total Marks. = 240 *100 / 400 = 60%
According to math for finding percentage is to divide the numerator by the denominator then multiply the output with 100. Suppose you want to find the percentage of 50/100 then divide 50 with 100 the answer will be 1/2 the multiply 1 * 100 / 2 = 50%
