Writing Decimals as Percents Unit 4 > Lesson 3 of 9

Problem: What percent of a dollar is 76 cents?   [IMAGE]
$1.00 = 1.0
76 cents = .76
.76 = 76%
Solution: 76% of a dollar is 76 cents.

The solution to the above problem is not surprising, since dollars, cents and percents are all based on the number 100. To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right. This is done in the example below.

Example 1: Write each decimal as a percent:    . 93,    .08,    .67,    .41
 
Solution
Decimal Percent
.93 93%
.08 08%
.67 67%
.41 41%

Each decimal in Example 1 went out two places to the right of the decimal point. However, a decimal can have any number of places to the right of the decimal point. Let's look at Examples 2 and 3 below.

Example 2: Write each decimal as a percent:     .786,    .002,    .059,    .8719
 
Solution
Decimal Percent
.7860 78.6%  
.0020     .2%  
.0590   5.9%  
.8719 87.19%


Example 3: Write each decimal as a percent:     .1958,     .007,    .05623,    .071362
 
Solution
Decimal Percent
.195800  19.58%    
.007000       .7%        
.056230    5.623%  
.071362   7.1362%


Summary: To write a decimal as a percent, multiply it by 100, then add on the % symbol. To multiply a decimal by 100, move the decimal point two places to the right. Do not forget to include the percent symbol when writing a percent.
