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%.
If a student gets 3 questions wrong on a 20-question test, they answered 17 questions correctly. To calculate the grade, divide the number of correct answers (17) by the total number of questions (20) and then multiply by 100 to get a percentage. This 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".
88%, or a B+
77% or C+
As a percentage it is 80%
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. :)
