80 percent, this is easy, even for a guy who did summer school twice for math related subjects.
100 questions = 20% so 1 question = 20/100 = 0.2%
20
20 questions = 100% 19.2 questions = 96% its impossible to get 96% on a 20 question test. If you don't get 100%, then the best you can get is 95%.
80 out of 100 is 80/100, so 80%
81.8% 54/66 * 100= % right
You'd be 100% right.
-- Since she answered 86 percent of the questions correctly, she answered the remaining 14 percent of them incorrectly. -- 14% of 100 questions is 14 questions.
100 questions = 20% so 1 question = 20/100 = 0.2%
20
If you received a 5 percent on a test that just means for every 100 questions you got 5 right so a fraction of 5 percent would be: 5/100 so if you simplify that fraction you get --> 1/20
72%
You study very hard or overnight and you can get a 100% on the test next day!
20 questions = 100% 19.2 questions = 96% its impossible to get 96% on a 20 question test. If you don't get 100%, then the best you can get is 95%.
17 percent wrong, 83 percent right.
80 out of 100 is 80/100, so 80%
81.8% 54/66 * 100= % right
You divide the number of questions you got right by the number of questions there are then multiply the answer by 100.
