To determine productivity, we'll analyze how much the worker produced per hour. We're given two ratios: $\"160%2F40\"$ for the first week, and $\"138%2F36\"$ for the second. Since $\"160%2F40+=+4\"$ , 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 $\"138%2F36+=+3.83333...\"$ , we can state that the worker produced about 3.83 units an hour during the previous week. Since $\"4+%3E+3.83\"$ , the worker was more productive during the first week. \n" ); document.write( "
