First of all, remember that one ton= 2000 pounds.
Since the adult whale weighs 120 tons, multiply this by 2000 to find the number of pounds. 120*2000=240,000 pounds.
A baby whale weighs 1/40 of the adult whale's weight. Multiply 1/40 times 240,000 to find the total weight in pounds of the baby whale. [tex] \frac{240000}{1} * \frac{1}{40} = \frac{240000}{40} = 6000[/tex]
The baby whale weighs 6000 pounds.
