To convert a number to a percentage multiply by 100 %
→ 21/27 = 21/27 × 100 %
= 77 7/9 %
= 77.777... %
≈ 78 %
21%
It is 77.8% rounded to one decimal places
To work out the percentage of, for example, 21 correct answers out of 30 questions, do the following: 21 ÷ 30 × 100 = 70 (add the percentage sign, thus: 70%)(If the answer had been 0.70, ignore the 0. and use 70 as the percentage.)
81%
% rate = 28.57% =6/21 * 100% = 0.2857 * 100% = 28.57%
100*(21/25) % = 84%

There are so many uses it boggles the mind. I will list a few, and perhaps people will add to it over time. * Setting and calculating discounts on sale items at the store * Calculating sales tax * Test scores (percentage correct) * Political polling Rates, and percentage is just a rate (per 100), are useful wherever you want to express one value relative to another value. Percentages become especially useful if you want to compare groups on a fairer basis. For example, if Student A gets 18 questions out of 20 correct and Student B gets 21 questions out of 30 correct, which is the better student? Student B answered MORE questions correctly, but Student A is better because they achieved a higher PERCENTAGE of right answers (18/20=90%). Student B's score, expressed as a percentage, is lower (21/30=70%). But if I had 2 questions and answered them both correctly, I'd be better (2/2=100%)
21/28 = 3/4 = 75%
