The water district needs to store 4,000,000 gallons of water for the summer. Each of the district's water tanks can hold 800,000 gallons of water. How many tanks will the water district need to use?

Answer 1

To find the number of tanks the water district needs to use, we divide the total amount of water needed by the capacity of each tank:

4,000,000 gallons / 800,000 gallons/tank = <<4000000/800000=5>>5 tanks.

Therefore, the water district will need to use 5 tanks.
