Answer: The answer is 152!
Explanation:
Lets let x represent the total population of fish in the pond. The ratio of tagged fish to the total fish population is therefore 24 : x
Assuming this ratio of "tagged to total" will be found for whatever number of fish get caught would mean that the ratio of "tagged to total" in the catch is the same as the ratio of "tagged to total" for the pond.
We can solve this type of problem with a proportion: Substituting in the numbers we get: Solving proportions such as these involves cross-multiplication 3x = (19)(24) After dividing both sides by 3 to isolate x we see that x = 152
