Give the step-by-step reasoning process and then the final answer. The largest animal to have ever lived on earth is the blue whale. The tongue of an adult blue whale can weigh 6000 pounds. If one ton is 2000 pounds, how many tons can the tongue of an adult blue whale weigh?
1000 pounds more than 5ooo pounds is 6000 pounds. If one ton is 2000 pounds, then the tongue of a blue whale weighs 6000 / 2000 = 3 tons.
The final answer: 3.
