Percents are easier since they don't need to be converted. It saves a step.
you eat pie
when you are specifically comparing 2 sets of data (2 #'s, 2 percents, 2 rates ect.)
Divide by 100.
I'm not sure...
Because percentages can be expressed as fractions which are rational numbers
Percents are basically decimals, and we use decimals as numbers with extra, tiny proportions. Percents are just ways to make those decimals into a whole, more friendlier number. But, percents can also be made with decimals as well.
They are ways to represent numbers.
divide the two numbers then divide
how you compare decimals and percents, is by the signs. a decimal looks like this: 0.0 and a percent looks like this: %
by simplifying the given numbers
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.
They are all ways of representing numbers.
It is easier to understand rates of changes as percents, sometimes, than as a fraction. Such as the stock market fell 70%Also, you can compare percents and fractions are a little harder to compare. For example you got 91 percent right on your test and your friend took a similar test with twice as many problems and got 83% right. It is easy to compare the percents.There are many other reasons!
It is finding an equivalent number whose denominator is 100.
First you have to compare the whole numbers. When the whole numbers are the same, compare the fractions. If the denominators of the fraction are the same, compare the numerators. If the denominators are different, convert them to have the least common denominators. Then compare the numerators.
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%.
You can compare their magnitude (absolute values) but not the numbers themselves.
They are called rational numbers
They need not be. The length of a unit square, as a percentage of its diagonal is NOT a rational number.
The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.
No one invented percents.
