It is quite simple to convert a percentage to a decimal fraction. Just move the decimal point two spaces to the left. So, 50% becomes .5 and 75% becomes .75 and half a percent (.5%) becomes .005 and 100% becomes 1. Percentage, remember, means out of a hundred. So 50% is 50 out of a hundred, which is half. And as a decimal, half is .5 which you can derive simply by moving the decimal point.

In order to convert decimals into percentages In order to convert decimals into fractions To distinguish irrational numbers from rational numbers

Decimals and percentages are easier to compare than fractions - particularly if they are unlike fractions. That does not explain why percentages are required when we have decimal number and there is no good answer to that!
How do you do compare and order fractions and mixed numbers?
It may be simplest to convert them all to a common form: rational fractions, decimal fractions or percentages and then compare them. When you are more expert, you may be able to convert them pairwise into a common basis and compare.
How do you convert decimal percentages to fractions?
98.0% = 98.0/100 = 980/1000 = 98/100 = 49/50 45.684% = 45.684/100 = 45684/100000 = 22842/50000 = 11421/25000 Thus you can convert any decimal percentage to fraction
How do you order unlike fraction?

How do you add fractions with unlike denomanators?
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.
How do you order unlike fraction?
The simplest way is to convert them to like fractions, or percentages.
What is percent 80 is 100?
When calculating with percentages, one method is to first convert them to decimals or fractions. Using the decimal method, 80%=0.8 and 100%=1. Therefore, the literal translation of you question would read "0.8 x 1 = 0.8". 0.8 is the decimal answer. If you wanted a percentage answer, you would convert this back to 80%. Kind of a nonsense question, though. You usually do not take percentages of percentages.
What is the link between percentages and fractions?
divide to change the fraction into a decimal and multiply by 100 to change the decimal to a percent.
How are fractions related to percentages?
Starting from a decimal fraction, a percentage is simply the decimal fraction with the decimal point moved two place to the right.If you have a rational fraction, you convert it to an equivalent fraction whose denominator is 100. Then the numerator of that equivalent fraction is the percentage.
When dealing with percentages can a decimal be involved?
percentage is a fraction of 1 with a denominator of 100, eg 45 % is 45 / 100 or 0.45 in decimal you can interchange the values of percentages, decimals and fractions, each is just a more convinient way of saying the same thing, percentages tend to be in the money world, straight decimals are for arithmetic and generally fractions are pre decimal
