0.33% (rounded up from 0.329)
(84 -11)/84 = 73/84 = .87 Grade is an 87, or B+
100 - (1/11) = 99.90 recurring (that is, 99.909090...) percent.
If you missed out 11 AND got all the rest correct you would have 83.08%. However, if you miss out 11 out of 65 it is unlikely that you are good enough to get all the rest correct!
11/12 right = 92%
50/50 - 11/50 = 39/50 39/50 x 2/2 = 78/100 = 78%
64.52% right. Call it 65%
86.25% To verify: Divide number of incorrect questions (11) by number of original questions (80); answer expressed as a percentage is 13.75%. That's the number of incorrect answers, therefore 100% - 13.75% = 86.25% is the number of correct answers.
Oh, dude, let me do the math for you. So, if Emily answered 11 questions wrong out of 65, we just divide 11 by 65 and multiply by 100 to get the percentage. That's like around 16.9%. So, yeah, Emily missed about 16.9% of the questions on her test. Cool, right?
83% right.
