Need the monthly averange of number of orders I place correctly.

Question

I'm trying to figure out an average here. It needs to be such as 99.58% or 97.45% (NOT 95 %) I need to show all four place values. So if I place 200 orders a month and 2 are wrong.  2/200 =.01  What is my average orders that I place right in the month?

Answer 1

You are correct that 2/200 = .01 = 1.00% wrong, so the percentage of orders right is 100% - 1.00% = 99.00%  

 

Or you could divide the number of right orders by the total orders to get 

 

198/200 = 0.99 = 99.00%
