do you have a specific question?

OpenStudy (anonymous):

Not really I just need to know how to work out percentage off a number for example ' John has 52 cards work out the percentage off getting a king' What do you times and divide it by?

OpenStudy (anonymous):

4 kings, 52 cards take \(\frac{4}{52}\) or if you prefer \(\frac{1}{13}\) as for a percent, take a calculator, compute \(1\div 13\) and then move the decimal 2 spaces right
