it's basically telling you to change it into an improper fraction because a fraction is a ratio.
----------------------
to change it into an improper fraction, multiply the denominator (5) with the whole number (2) and you get 10. to this (10) add the numerator, which is 3. and you get 13. leave the denominator as is and you get 13/5.
