Let x= the size of thge smaller tank
Then,
2x= the size of the bigger tank(one tank needs to be twice the size of the other)

Their sum is x+2x
x+2x=400------------------Two tanks must have a total capacity of 400 gallons
3x=400
x=400/3 or 133.33
2x= 266.66
Therefore, the tanks must hve sizes, 133.33 and 266.66 gallons!
