Hi,

One hundred forty alligators are captured, tagged, and then released into the Florida Everglades. 

Later, 200 are recaptured, and of these, 40 are tagged. 

What is the approximate number 'x' of alligators in the Everglades? 

40%2F200+=+140%2Fx   |Cross Multiplying to solve

40x+=+140%2A200

     x = 700 alligators in the Everglades
