Final answer:
To find the number of fish left in the pond after 5 days, subtract the number of fish the crocodile eats each day from the initial number of fish. There will be 225 fish left in the pond after 5 days.
Step-by-step explanation:
To find the number of fish left in the pond after 5 days, we need to subtract the number of fish the crocodile eats each day from the initial number of fish.
The crocodile eats 15 fish each day for 5 days, so the total number of fish it eats is 15 * 5 = 75.
To find the number of fish left, we subtract 75 from the initial number of fish, which is 300. Therefore, there will be 300 - 75 = 225 fish left in the pond after 5 days.
