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.
5% of 85 = 85/100 x 5= 0.85 x 5= 4.25
At most 16 questions. Percent means "out of 100" → 85% of 108 = 85/100 × 108 = 91 4/5 Which means unless you get 92 you will not get at least 85 % Therefore you can miss out on 108 - 92 = 16 questions at most and still get at least 85 %
percent is just another way of saying "out of 100". So 85% is 85 out of 100, or as a fraction 85/100. That can then be simplified by a factor of 5 to give 17/20.
(5/62)*100 = 8.07% wrong.

85% of 5 years = 85% * 5 = 0.85 * 5 = 4.25 years OR 4 years 3 months
% rate = 85/1700 * 100% = 5%

(77+83+89+86+x)/5=85 (335+x)/5=85 (335+x)=85*5 335+x=425 x=425-335 x=90 He must get 90% on his fifth test to average 85%.
85% means 85/100 = reduced to 17/20 factor out 5
Subtracting 20 percent from 85 gives 85 x (1 - (20/100)) = 85 x 0.8 = 68
percent is just another way of saying "out of 100". So 85% is 85 out of 100, or as a fraction 85/100. That can then be simplified by a factor of 5 to give 17/20.
85% = 17/20 Because 85%= 85/100 85/100 divided by 5 is 17/20
