PERCENTS
Percents are used to describe a part of something. Percents are used to figure out sales or the amount of interest someone will pay on a
loan. When converting a percent to its fraction form, it will always have a denominator of 100.
Changing Decimals to Percents or Percents to Decimals
The important key is where to move the decimal point. If changing from decimal to a percent , you would need to move the decimal
point two places to the right and add the percent sign.
Example: 0.35 = 35%
0.8 = 80%
To change from percent to decimal, need to move the decimal point two places to the left and drop the percent sign.
Example: 30% = .3
0.9% = .009
Converting Fraction to Percent Form
Divide the bottom number of the fraction into the top number and move the point two places to the right.
Example:
.75
4 3.00 = .75 = 75%

Write the percent as a fraction with 100 as the denominator. Then
reduce the fraction to lowest terms.
