For example, each person recycles 1.8 kilograms of waste paper, and there are 1,100 students in our school. How many tons of recycled paper can be produced from the waste paper recycled by the students? Recycling 1 kg of waste paper can produce 0.8 kg of recycled paper.
如每人回收1.8千克废纸，我校共1100名，同学回收的废纸可生产多少吨再生纸？回收1千克废纸，可生产0.8千克再生纸．
