A public aquarium built to contain neon tetras. Each neon tetra needs 1.25 gallons of water. The aquarium will contain 1 times 10^5 gallons of water. How many tetras can it house? Write the answer in scientific notation.
To calculate how many neon tetras can be housed in the aquarium, we need to divide the total volume of water in the aquarium by the amount of water needed for each neon tetra.
Number of tetras = (1*10^5) / 1.25 = 8*10^4
Therefore, the aquarium can house 8*10^4 neon tetras.
