in a certain pond , 100 fish were caught , tagged , and returned to the pond . a few days later , 100 fish were caught again , of which 2 were found to have been tagged . if the percent of tagged fish in the second catch approximates the percent of tagged fish in the pond , what is the approximate number of fish in the pond ?
"total fish = x percentage of second catch = ( 2 / 100 ) * 100 = 2 % so , x * 2 % = 50 x = 2500 ans . d"
divide(100, divide(2, 100))
