To convert from decimal form to percent form, multiply by 100%. Note: Multiplying by 100% has the same result as moving the decimal point two places to the right and adding the percent sign.

Example:

Write 0.64 in percent form.

Solution:

Multiply 0.64 by 100%.

0.64 x 100% = 64%

To convert from percent form to decimal form, drop the percent sign and move the decimal point two places to the left.

Example:

Write 5.2% in decimal form.

Solution:

Drop the percent sign and move the decimal point two places to the left.

5.2% = 0.052
