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.

Answer 1

To find out how many tetras can the aquarium house, we need to divide the total volume of water in the aquarium by the volume needed for each tetra.

The aquarium has a volume of 1x10^5 gallons of water.
Each tetra needs 1.25 gallons of water.

So, the number of tetras the aquarium can house is given by:

1x10^5 gallons ÷ 1.25 gallons/tetra

Simplifying, the gallons unit cancels out, leaving only the numerical value:

1x10^5 ÷ 1.25

Calculating this, we get:

8x10^4

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