Percents and Decimals

The word percent means “hundredths” or “divided by 100 .”  The symbol % is used to represent percent.

To convert a percentage to a decimal, remove the percent sign and divide by 100 .  (You can achieve the same result by moving the decimal point two places to the left.)

To convert a decimal to a percentage, multiply by 100 and add a percent sign.  (You can achieve the same result by moving the decimal point two places to the right.)

            0.065=6.5% 3.75=375%

To change a fraction into a percentage, divide to find its decimal equivalent and then change the decimal to the percentage.
