HELP, please....
Out of 200 fish in an aquarium, 99% are guppies. How many guppies must be removed so that the percentage of guppies remaining in the aquarium is 98%?
Look at it this way.... Beforehand, 198 of the 200 fish were guppies (99% of 200 fish = 198 guppies.) Afterward, 98 of the 100 fish will be guppies (98% of 100 fish = 98 guppies). Got it?
