Asked by Santana

A biologist wants to estimate the number of fish living in a lake. She caught 106 fish, tagged each one, and then released them back into the lake. After a few days, she caught 227 fish, and found that 11 of them were tagged. Use a proportion to estimate the number of fish living in this lake.
