100 divided by 5 is 20. 100 minus 20 is 80. The answer is 1.

17 percent wrong, 83 percent right.

30/100*25 =7.5 so you must not get more than 7 questions wrong to score 70%

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.

if you get 22 questions wrong, you will have a 78%. less then 22 wrong would mean a higher percentage and more then 22 wrong would mean a lower percentage.

100/9 = 11.11 %

100*4/22 = 18.1818... (recurring) % wrong.

10 is the answer,because 100 - 80 = 20 divide that by 2 and you get the answer. 50 - 40 = 10

The answer depends on whether or not there are penalties (negative marks) for wrong answers. If not, then the answer is 30.

93.85% (61/65,*100)
