OK, now I don't know how old you are to be asking some thing like this, but the reason for this is so that when you are comparing some thing in high detail it is can be easier to do it in percent. For example if your comparing very small numbers like 18.059% you can make it more detailed. And for on-line ratings, you can use percent instead of a fraction to make it easier, such as 87% good feed back
hope I helped :D
Because in today's world things are usually compared by percentages, for example, out of 400 people surveyed only 100 gave their answer. Then you would take 100 and divide it by 400 to get a percentage. Then you would be able to say out of 400 people surveyed only 25% gave their answer. Take for example the polls on Fox News. they usually have a question for the day and by the end of the day they can say out of 46,000 people taking the survey only 25% say Obama is doing a good job; 30% say he is not doing a good job and 45% have no comment. So you can see percentages are used everyday for millions of comparisons.
They are all the same, fractions can be turned into percents and percents can be turned into fractions. hope that helps :)
lawyers use percents when figureing out prices and taxes of houses
percents are used to dealing with math for example you can always do 45/100% wich reduces to 450%.
A circle that can measure percents.

comparisons
yes
"Lens" comparisons
I'll answer assuming you meant percent. Percents are the ratio of a number or fraction to 100, so 2% is 2 to 100. If you compare 29 and 1000 and you want to compare it through percents, convert 1000 to 100 by obviously dividing by 10. So, 29 / 1000 is 2.9%.

No one invented percents.
20 percents
percents are numbers over 100
Surely percents can always be expressed as fractions or decimals, but percents are useful for comparing values- percents are essentially fractions all of the same denominator so they are easier to compare. Example: which is bigger 9/20 or 88/200 ? which is bigger 45% or 44% ? The percent question is easier to answer even though the numbers are the same.
urm....NO you Hitler
i believe the answer is.... A strong OBSERVATION can be useful for making predictions
They are all the same, fractions can be turned into percents and percents can be turned into fractions. hope that helps :)
