69%. Just subract 31 from 100. 100-31=69.
Percentage of 28 out of 31 = 28/31 * 100% = 90.32%
percentage = 9.68%% rate:= 3/31 * 100%= 0.0968 * 100%= 9.68%
31/38 = .8158 x 100 = 81.58%
( | V1 - V2 | / ((V1 + V2)/2) ) * 100
Well, isn't that just a happy little math problem! To find the percentage, you simply multiply 31 by 2 to get 62. Then, you add a percent sign to the end to make it 62%. Just like that, you've turned 31/50 into a lovely percentage!
If every question was worth the same credit, then your score was 25.8% wrong 74.2% correct
% rate:= (31/105) x 100%= 0.2952 x 100%= 29.52%

15/49 (x100)= 31% missed; you got 69%.
Percentage of 28 out of 31 = 28/31 * 100% = 90.32%
percentage = 26.05%% rate:= 31/119 * 100%= 0.2605 * 100%= 26.05%
percentage = 9.68%% rate:= 3/31 * 100%= 0.0968 * 100%= 9.68%
percentage = 48.39%% rate:= 15/31 * 100%= 0.4839 * 100%= 48.39%
percentage = 86.11%% rate:= 31/36 * 100%= 0.8611 * 100%= 86.11%
percentage = 58.06%% rate:= 18/31 * 100%= 0.5806 * 100%= 58.06%
100 - 69 = 31, and it's percent, so it's .31 .31*30 = 9.3, but you must round down or up (down to get more than 69%), so you can miss 9 questions and still fail.
5 as a percentage of 31 = 100*5/31 = 16.13%, approx.
