Answer:
0.028 goldfish/person
Step-by-step explanation:
The number of goldfish per person is found by dividing the number of goldfish by the number of persons:
17500 goldfish/(625000 persons) = 175/6250 goldfish/person
= 7/250 goldfish/person = 0.028 goldfish/person

Additional comment
In the context of math ratios, "per" essentially means "divided by". "Per capita" means "divided by the number of people."
