Percents<br />
Percents<br />
Percent is another way to describe a part or fraction of something. The only<br />
denominator that a percent can have is 100. This denominator is shown by a<br />
percent sign %. The word percent and the sign % both mean hundredths.<br />
For example: 25% is the same as 25/100 or 1/4 or .25<br />
Although percent means out of one hundred, a percent can be more than 100. A<br />
percent larger than 100 is equal to an improper fraction. When working with<br />
percent problems, you need to change the percent to a decimal or fraction.<br />
Changing Percents to Decimals<br />
Here is how to change 85% to a decimal:<br />
1. Drop the percent sign. 85<br />
2. In a number with no decimal point, it is understood that the decimal point<br />
is at the end of the number. Put in the decimal point. 85.<br />
3. Now that you have a decimal point, move it two places to the left. 0.85 =<br />
85% = .85 = 85 hundredths<br />
The tricky part is putting in the decimal point. Study these examples:<br />
• 5 % = .05<br />
• 10% = .10<br />
• 55% = .55<br />
• 3% = .03<br />
