82.4% or B
To calculate the grade, divide the number of correct answers by the total number of questions: (20 - 3 = 17) correct answers. Then, calculate the percentage: (\frac{17}{20} \times 100 = 85%). Therefore, getting 3 questions wrong out of 20 results in a grade of 85%.
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".
As a percentage it is 80%
88%, or a B+
77% or C+
10/13 right = 77% grade
77% or C+
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+.
Grade 3/4 Also, I think you put this question in the wrong category. :)
