Are fractions better than decimals?
I Think Decimals Are Better Than Fractions
Why is a fraction of pi better then the decimal of pi?
Since pi is an irrational number it is impossible to represent the exact quantity as a decimal; you can only give and approximate value. However, if you write a fraction that includes the symbol for pi, you are giving an exact quantity.
What is percentage analysis?
percentage analysis is the method to represent raw streams of data as a percentage (a part in 100 - percent) for better understanding of collected data.
When is a percent more preferred to be used over fractions or decimals?
When working with statistics, or otherwise when presenting numbers to others, I'd say.It's easier to imagine the "meaning" of percentages, than some of the more difficult fractions, or long unwieldy decimal numbersWhilst calculating though, fractions (or decimals, if you can get them to be exact without having a page full ;P) are allways better.
Why use mixed numbers in fractions?
In a practical sense, sometimes it is better to have whole units rather than just pure fractions. it gives a better idea of "how big" is the thing. Having only fractions could be hard to compare (and thus make decisions based on those measurements)
