Why are percents useful in making comparisons?

Answer 1

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.
