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 miss 5 questions on a 20-question test, you answered 15 questions correctly. To find your grade, divide the number of correct answers (15) by the total number of questions (20) and then multiply by 100 to get a percentage. This results in a grade of 75%.
65% or D
95.0%
every question is 2 points
If you got 20 problems wrong on a 75 question test your grade would be 73% or a C. You can find that by subtracting the amount of questions you got wrong from the amount you got right, 55 in this case. Divide the amount of correct questions by the amount of questions on the test to get .733333. That is the grade.
a B
If there are 20 questions then each question is worth 5 points because 100 total points divided by 20 equals 5.If you missed 8 questions then 8 times 5 points equals 40 points wrong, so you have to subtract that from 100 to get a grade of 60. Study harder next time.
