7/13. These numbers have no common factors (besides 1), so it's as simple as putting one over the other.
The order that you typed the expression "ratio of trucks to cars" is important. Whichever word came first, its number must come first. You have written it both ways, but using the expression "15 cars to 23 trucks" could be written in odds notation as "15:20" or fractional notation as "15/23".
This means that you should write your answer using fractional notation as opposed to decimal notation. For example, you would write 1/4 instead of .25 .
