Percents and Decimals

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

      39 % means 39 divided by 100 or ( 39 100 )

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.)

      16.2 % = 0.162 25 % = 0.25

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.

      15 20 = 0.75 = 75 %
