You can simplify it by finding the Greatest Common Factor and dividing the numbers by the GCF.
60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 30, 60
25: 1, 5, 25
The greatest common factor is 5.
Divide both sides by 5.
60/5=12

A ratio that is equivalent is 12:5

Hope I helped!

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
