A public aquarium is being built to contain neon tetras needs 1.25 gallons of water. The aquarium will contain 1 × 10⁵ gallons of water. How many tetras can it house? Write the answer in scientific notation.

1 answer

The number of neon tetras that can be housed in the aquarium is given by dividing the total volume of water by the volume of water required for each tetra:

Number of tetras = Total volume of water / Volume of water required for each tetra

Number of tetras = 1 × 10⁵ gallons / 1.25 gallons

Number of tetras = 8 × 10⁴

Therefore, the aquarium can house 8 × 10⁴ neon tetras.
