you are getting a larger aquarium for your neon tetra fish and you also want to add more tetras to the larger aquarium. The general rule is that each fish needs 2 gallons of water. You currently have 6 neon tetras. If you buy a 20-gallon aquarium, what are the possible numbers of fish you can put in your aquarium? Explain your answer



Answer :

6 x 2 = 12     (2 gallons x 6 fish)

20 - 12 = 8      (20 gallons - 12 gallons)

8 / 2 = 4        (8 gallons / 2 gallons per each fish)

6 + 4 = 10        (6 original fish + 4 new fish)


So you can have 10 fish in total.


Or just do...

20 / 2 = 10      (20 gallons / 2 gallons per fish) = 10 fish
