You can make the proportion into a percent by dividing the numerator by the denominator and then moving the decimal point two spaces over to the right. That's your percent.
Also if the denominator is a factor of 100, you can set it to a hundred. Example:
2/5=40/100. So the percent is 40%, the numerator over 100.
