Solution: each set of clothing fabric is 3.6 meters, which can be made into 120 sets, so it is easy to know that a * * * fabric is 3.6* 120=432 meters. Each set of clothes saves 1/9, so the fabric of each set of clothes is 3.6 * (1-1/9) = 3.6 * (8/9) = 3.2 meters, so one * * can make [432/3.2] sets. [] means rounding.
