Question 56972
Assume all ants are 8 millimeters long and weight 7 milligrams each.  Find the number of kilograms in the weight of a string of ants one kilometer long.  Explain your answer.
------------------
1 km = 1000 meters = 1,000,000 millimeters
1,000,000mm/8mm = 125000 ants in 1 km
125000*7 mg = 875000 mg = 875 kg
The ants weigh 875 kilograms.
