At the aquarium, there are twice as many sharks as stingrays. If there are 28 stingrays, how many fish are there?

How many sharks are there? ** If sharks are twice the number of stingrays, then the number of sharks at the aquarium is 2 sharks/stingray * 28 stingrays = <<2*28=56>>56 sharks
How many fish are there? ** The number of fish in the tank is 56 sharks + 28 stingrays = <<56+28=84>>84 fish
