How to Convert Percents into Decimals
Changing Percents into Decimals
Many times people will need to learn how to do percents in some areas of life, such as job interview tests, pre-college tests, basic school classwork and tests, and as an on the job skill. Practicing percents is easy once you keep practicing.
The % sign represents hundredths. And the % sign means 2 decimal places. To express a percent as a number for a decimal fraction, we rewrite the digits of the given percent but drop the percent sign. Then we move the decimal point two places to the left. A decimal point is understood after the ones digit in a number naming a whole number.
Show 23% as a decimal number: 23 % = .23
If the percent is a decimal percent such as 15.2%, the answer contains more than 2 decimal places.
Example: 15.2% = .152
When the percent is 100% or more, the answer is a number naming a whole number or a mixed decimal.
Sample of a whole number: 300% = 3
Sample of a mixed decimal: 136% = 1.36
And when a percent is a common fraction less than one percent such as 1/2%, the answer may be written as a two-place decimal number .001/2 (or as .005 since 1/2% = .005).
Converting Percents into Decimals
Also when a percent is a mixed number percent such as 18 3/4% (eighteen and three quarters), the answer may be written as a two-place decimal number .18 3/4 (or as .1875 since 18 3/4% = 18.75% = .1875).
For practice show each percent below as a decimal number:
- 24%, 60%,12%
- 4%, 9%, 1%
- 35%, 30%, 70%
- 131%, 127%, 100%
- 140%,110%, 232%
- 60 1/2%, 3 1/4%, 30 1/3%, 1/8%
- 21.5%, 4.2%, 0.1%, 0.785%
Now show each of the following percents as a number naming a whole number:
