Set up the following proportion:
# of questions wrong / total # of questions in the test
Given that 12 questions out of 26 are answered incorrectly, we set up the ratio as:
12 / 26
We can simplify that fraction to:
(2 x 6) / (2 x 13)
= 6 / 13
Multiply that value by 100 to obtain 600 / 13 % which is approximately 46.2%
19/20 as a percentage = 100*19/20 = 95%
If there are forty and you got twelve wrong, then you got twenty-eight correct. 28 out of 40 = 70%
4% wrong
40 percent wrong questions. To calculate the percentage 6 divided by 15 and multiplied by 100.
if you get 22 questions wrong, you will have a 78%. less then 22 wrong would mean a higher percentage and more then 22 wrong would mean a lower percentage.
percentage of 1 wrong out of 85 questions = 1.17% % rate: = 1/85 * 100% = 0.0117 * 100% = 1.17%
percentage of 10 wrong out of 36 questions = 27.78%= 10/36 * 100%= 0.2778 * 100%= 27.78%
percentage of 2 wrong out of 120 questions = 1.67%% rate:= 2/120 * 100%= 0.0167* 100%= 1.67%
84
21%
75% right, 25% wrong.
You got 91.66% right, and 8.33% wrong
