How do you write percents as fractions? - Answers

1. IF the original fraction has a denominator (bottom number) that is a factor of 100 (in other words you can multiply something with the denominator to get the answer of 100), you can use the following procedure to turn it into a percent. a. Figure out what number has to be multiplied with the denominator to make 100. Now, multiply both the numerator (the top number) and the denominator (the bottom number) with the special number required to get 100. EX: 3/25 Hmmm, I'd need to multiply 25 (4) in order to make 100. So, I'll multiply both the top and the bottom of the fraction by 4. 3/25 X 4/4 = 12/100. b. Now I've renamed 3/25 as 12/100. "Percent" means "for every 100". The new fraction tells me there are 12 for every 100. So, the percent equivalent for 3/25 is 12% 2. IF the original fraction's denominator (bottom number) is not a factor of 100 (in other words, there isn't anything you can multiply with it to get 100), then you'll need to use division to find the percent equivalent. This is trickier and requires you to know how to divide by hand, or you can use a calculator. a. You will divide the denominator (bottom number) into the numerator (top number). EX: 4/7 = ? % 4 divided by 7 is 0.5714 (the decimal actually goes on longer than this) b. Now that you have a decimal, move the decimal point two places to the right. The percent for the above decimal is 57.14% Hope this helps.
