To determine productivity, we'll analyze how much the worker produced per hour. We're given two ratios: for the first week, and for the second. Since , we can say that the worker produced 4 units per hour during week 1, since we are dividing units over time (and our measurement of time is hours). Also, since , we can state that the worker produced about 3.83 units an hour during the previous week. Since , the worker was more productive during the first week.
