How do you make a decimal a percent? - Answers

Here's an example:Express: .89 as a percent. Move the decimal over two places: (.89 to 8.9to 89.) then use the percent sign, leaving you with 89% If you want to turn it back into a decimal, just move the decimal (in this case, the percent sign) two spaces to the left, leaving you with .89 again.For three digit or more, you can do the exact same thing. Just always move the decimal twice to the right for percents, and always move it twice to the left for decimals.Express: 4.692 as a percent: well, we move the decimal twice to the right... making it 469.2% If you want to turn it back into a decimal, just move the current decimal twice to the left, giving you back your 4.692.
