Hello All ! I have two "series" of data : The first serie are "normal values" The seccond serie represents a percentage(Value) of an amount(Nominator) Serie 1) Value Nominator 100 1 150 1 125 1 Serie 2) Value Nominator 10 100 12 200 15 300 The Problem: -------------------------------------------------------------------------- I want to find a GENERAL formula to calculate the SUM of these series, So a formula which gives the following results Serie 1) 365 Serie 2) 13,1 Explanation results: Serie 1) 100+150+125 = 375 serie 2) 10% of 100 = 10 12% of 200 = 24 15% of 300 = 45 So total amount = 600 and the fraction=79 so that is 13.1% What is the general formula (using value and nominator) ????????? Thank you very much !!!
