Both are correct but I would like to provide you with one more things to consider. It is when the percent is converted to a repeating decimal. If you have a percent that turns into a repeating decimal, then it needs to be over 9. For example. .11111.... should written as 1/9 but if the percent converts to something like .424242... then it needs to written as 42/99. After the fraction is set up, it is also important to reduce again.
