Question 400700
To determine the number of deer in a game preserve, a conservationist catches 300
 deer, tags them and lets them loose.
 Later, 300 deer are caught, 165 of them are tagged. How many deer are in the preserve?
:
Write a ratio equation: let d = actual number of deer:
{{{300/165}}} = {{{d/300}}}
165d = 300 * 300
165d = 90000
d = {{{90000/165}}}
d = 545 deer
