A public aquarium is being built to contain neon tetras. Each neon tetra needs 1.25 gallons of water. The aquarium will contain 1 x 10^5 gallons of water how many tetras can it house write the answer in scientific notation

To find out how many tetras can the aquarium house, we divide the total amount of water in the aquarium by the amount of water each neon tetra needs.

Total amount of water in the aquarium: 1 x 10^5 gallons
Amount of water each neon tetra needs: 1.25 gallons

Therefore, the number of neon tetras the aquarium can house is:

(1 x 10^5 gallons) / (1.25 gallons) = 8 x 10^4 tetras.

The answer, written in scientific notation, is 8 x 10^4.
