A public aquarium is being built to contain neon tetras. Each neon tetra needs 1.25 gallons of water. The aquarium will contain 1x10^5 gallons of water. How many tetras can it house? Write the answer in scientific notation.

1 answer

To find the number of tetras the aquarium can house, we need to divide the volume of water in the aquarium by the volume of water needed per tetra.

Number of tetras = (Volume of water in aquarium) / (Volume of water needed per tetra)

Number of tetras = (1x10^5 gallons) / (1.25 gallons)

Number of tetras = 8x10^4

Therefore, the aquarium can house 8x10^4 tetras.
