Question: The average rat weighs half a pound. A rodent of unusual size weighs 37.5 pounds. What percentage of a rodent of unusual size's weight does the average rat weigh?
Answer: 1 1/3%
Solution: To find out what fractional part of 37.5 pounds a 0.5–pound rat is, we divide 0.5 by 37.5 to get 0.1
. A rat is therefore 1 1/3% the size of a rodent of unusual size.
