It depends on the grading scale. 47/50 is 94% which is an A in most cases.
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.
That is about a "C".
You got 75% correct.Reason:5 is 1/4 of 20, therefore meaning that you got 3/4 correct. And of course 3/4 = .75, or 75%
As a percentage it is 80%

It depends on the grading scale. 47/50 is 94% which is an A in most cases.
You can get at most 20% wrong. 20% of 16 is 16*20/100 = 3.2 Since you cannot get 0.2 questions wrong, the maximum possible is 3 questions.
You're permitted to give wrong answers to as many questions as you want to, and correct or blank answers to the rest of them. Unfortunately, however, the custom is that if you exceed some number of wrong or blank answers, then you fail the test.
