First you find out how many you got right by subtracting how many you got wrong from the total. So, 95-18 = 77
Then you divide the number correct by the total, so 77/95, which is about 81.1%
Then you apply the grading scale. In most cases, an 81.1% would be a low B.
If you get 2 wrong out of 20 then its a 90 percent
You would get a 77%. You do 14 (the amount you got right) divided by the total amount of questions (18). So 14/18 which equals 0.77777777...
That is 75%
to get a 90 you need to answer 56 questions right (6 wrong) to get an 80 you need to answer 50 right (12 wrong) to get a 70 you need to answer 44 questions right (18 wrong) to get a 60 you need to answer 38 questions right (24 wrong)
If you answered 27 correctly and 18 incorrectly, you would have answered 60% correctly.
If you get 2 wrong out of 20 then its a 90 percent
You would get a 77%. You do 14 (the amount you got right) divided by the total amount of questions (18). So 14/18 which equals 0.77777777...
To calculate the grade, first determine the number of correct answers by subtracting the wrong answers from the total: 95 - 18 = 77 correct answers. Next, divide the number of correct answers by the total number of questions: 77 / 95 ≈ 0.8116. To convert this to a percentage, multiply by 100, giving you approximately 81.16%. Therefore, the grade would be around 81%.
Subtract, to find out how many you got right. Then divide the right answers by the total questions, and multiply by 100. Note that this assumes:That the grade is calculated as a percentage.That all questions have the same "weight" or value.
That is 75%
78% or C+
86.7% or B
You can get 18 wrong.
77.7 %
First, take 18/32, which is about .563. Then multiply by 100, which is 56.3. So the grade is about 56.3%.
to get a 90 you need to answer 56 questions right (6 wrong) to get an 80 you need to answer 50 right (12 wrong) to get a 70 you need to answer 44 questions right (18 wrong) to get a 60 you need to answer 38 questions right (24 wrong)
To find the percentage of 18 out of 20 questions, divide 18 by 20 and then multiply by 100. This calculation gives you (18/20) × 100 = 90%. Therefore, 18 out of 20 questions is 90%.
