Answer 1

Answer:

9,000,000,000 gallons of water.

Step-by-step explanation:

We have been given that a website recommends that you should have 3 gallons of water for every inch of goldfish in your tank. We are asked to find the gallons of water needed for one billion goldfish that are each 3 inches.

First of all, we will find gallons of water needed for each fish.

$\text{Gallons of water needed for each fish}=3\cdot 3=9$

$\text{1 billion}=10^9=1,000,000,000$

Now, we will multiply number of gallons of water required for 1 fish by 1 billion to find required gallons of water.

$\text{Gallons of water needed for 1 billion fish}=9\cdot 1,000,000,000$

$\text{Gallons of water needed for 1 billion fish}=9,000,000,000$

Therefore, you need 9,000,000,000 gallons of water for 1 billion fish.
