George wanted to buy some guppies for the aquarium. The owner of the tropical fish store told him that 6 square inches of air surface would be needed for each 2 guppies in the tank. How many guppies could George put into his aquarium if the tank had 180 square inches of air surface?

6 square inches for 2 guppies. If 6 square inches time 30 equal 180 inches then 2 guppies time 30 will be 60 guppies. The answer is 60 guppies
