Final answer:
The expression 1/2 divided by 1/6 represents sharing a pizza equally among 6 friends.
Step-by-step explanation:
The expression 1/2 divided by 1/6 represents the situation of sharing a pizza equally among 6 friends, with each person getting 1/2 of a slice. This can be visualized by slicing one pie into five slices and taking three of them, or slicing three pies into five equal pieces and taking one.
This expression does not represent dividing 1/2 of a cake into 1/6-sized pieces, finding the average of 1/2 and 1/6, or measuring the time it takes to run 1/2 of a mile in 1/6 of an hour.
