It depends on the problem. For instance, put simply, in a class of thirty children, if half had packed lunches, what percent is that? Half of 30 means that 15 children would be half or 50% of the whole class.

They are all the same, fractions can be turned into percents and percents can be turned into fractions. hope that helps :)
percents are used to dealing with math for example you can always do 45/100% wich reduces to 450%.
There is no single method. There are different methods for different problems.
Because you simply set it up in a proportion box, for example if you have the fraction 4/8 you put the 4 on top of the 8 and 100 next to the 8 because with percents you always use 100. then solve,
It really depends on the type of problem you are trying to solve. Did you have a specific problem in mind?
