Of the 50 fish that Christopher caught from the lake, 14 were trout. The estimated population of the lake is 7,500 fish. About how many trout would you expect to be in the lake?

Answer:2100

Explanation:

Okay, so 14/50 are trout, if we convert that into a decimal(divide 14 by 50) we get 0.28 which is the same as 28%.

Now that we have that we have that percentage, we just need to multiply it by 7500.

After multiplying you get 2100.

If 14 of the 50 fish were trout, we can write this as a fraction; 14/50.

To get this into an easier-to-understand form, we can multiply both sides by 2, giving us a fraction of 28/100. This means that 28 out of 100, or 28% of fish, will be trouts, at least for a rough expectation.

From there, we can multiply 28%, the percentage of trout, by 7,500, the total amount of fish in the lake.

7,500 x 28% = 2,100

Therefore, we can roughly expect about 2,100 of the fish in the lake to be trout.

Hope this helps! :)
