The elephants water tank holds 2560 gallons of water. Afterbtwo weeks the zookeeper measures and finds that the tank has 1944bgallons of water left. If the elephant drinksbthebsame amount of water each day how many days will a full tank of water last

2560-1944 = 616gallons

7 days in a week or 14 days in two weeks

616gallons / 14days = 44 gallons / 1 day

Notice in the fraction we have

(Gallons / days)

Now if you filled the take up the entire way

2560 gallons

We have gallons and the question wants the amount of days

Thus to cancel gallons we set the equation up as such

(2560 gallons) x (1 day / 44 gallons) = 58.18 days

Or 58 days

58.18 days is how long until a full tank is diminished.
