20-3 = 17 and 17/20 = 85/100 = .85 or 85%. Percent is a ratio per cent or 100. Multiplying both the 20 and the 17 by 5 will make the denominator 100 and the percent sought after.
If you have 20 questions and you get 3 wrong, that means you answered 17 questions correctly. Your score would be 17 out of 20. This can be expressed as a percentage by calculating (17/20) * 100, which equals 85%.
That is about a "C".

Grade 3/4 Also, I think you put this question in the wrong category. :)
To calculate your grade, divide the number of correct answers by the total number of questions. If you missed 3 out of 13 questions, you got 10 correct. Therefore, your grade would be 10/13, which is approximately 76.9%. Depending on the grading scale, this would typically be a C or C+.

The grade would be a "C."
