Percents Percents Percent is another way to describe a part or fraction of something. The only denominator that a percent can have is 100. This denominator is shown by a percent sign %. The word percent and the sign % both mean hundredths. For example: 25% is the same as 25/100 or 1/4 or .25 Although percent means out of one hundred, a percent can be more than 100. A percent larger than 100 is equal to an improper fraction. When working with percent problems, you need to change the percent to a decimal or fraction. Changing Percents to Decimals Here is how to change 85% to a decimal: 1. Drop the percent sign. 85 2. In a number with no decimal point, it is understood that the decimal point is at the end of the number. Put in the decimal point. 85. 3. Now that you have a decimal point, move it two places to the left. 0.85 = 85% = .85 = 85 hundredths The tricky part is putting in the decimal point. Study these examples: • 5 % = .05 • 10% = .10 • 55% = .55 • 3% = .03 NWT Literacy Council 65 65 Simply Math Workbook
Percents For example: Change 25 1/4 % to a decimal. 1. Drop the percent. 25 2. Change 1/4 to a decimal. 4 ÷ 1= .25 3. Put in the decimal point. 25.25 4. Move the decimal point 0.2525 two places to the left. The next example will show that when a percent like 100%, 200%, 300% etc. is changed to a decimal, the answer is a whole number. Here’s another example: Change 100% to a decimal. 1. Drop the %. 100 2. Put in the decimal point. 100. 3. Move the decimal point two places to the left. 1.00 =1 100% = 1 66 66 Simply Math Workbook NWT Literacy Council
