To determine how many pounds of soap powder a large station uses in a week, we need to establish the average usage per station and then apply the multiplier given in the question.

Let's assume an average station uses one unit of soap powder per week. Since the large station uses 1 1/12 times that amount, we first need to convert 1 1/12 into an improper fraction:

1 1/12 is equal to 13/12.

This means the large station uses 13/12 of the soap powder compared to an average station. If we multiply the average usage (1 unit) by 13/12, we find that the large station uses 13/12 units of soap powder per week.

To find the total usage in pounds, it is typically necessary to know the average amount of soap powder used per station in pounds. If we take an average use of 15 pounds, for example, the calculation would be:

15 pounds (average usage) x 13/12 = (15 x 13) / 12 = 195 / 12 = 16.25 pounds.

This also means a direct comparison could possibly yield a fixed choice. If we assume typical weights leading to
