[例1](南京市)日常生活中我们要科学地节约用水.现有一件刚用洗涤剂洗过的衣服,“拧干”后湿衣服上残留的溶液为100g,其中洗涤剂的质量分数为1%,则湿衣服上残留的洗涤剂质量为____g.现用5700g清水对这件衣服进行漂洗,有以下两种漂洗方法(假设每次“拧干”后湿衣服仍残留100g)溶液;方法一:用5700g清水漂洗,“拧干”后残留在衣服上的洗涤剂质量为(用分数表示)____g;方法二:用5700g清水均匀分成质量相等的三份(每份1900g),分三次漂洗;第1次,用1900g清水漂洗,“拧干”后残留在衣服上的
[Example 1] (Nanjing) In daily life, we need to save water scientifically. There is a piece of laundry that has just been washed with detergent. The solution remaining on the wet clothes after wringing is 100g, in which the mass fraction of the detergent For 1%, the quality of the detergent remaining on the wet clothes is _____g. The clothes are now rinsed with 5700g of fresh water. There are the following two methods of rinsing (assuming that after each wringing the wet clothes still have 100g of residual solution). Method One: Rinse with 5700g of clean water, the quality of the detergent remaining on the clothes after “squeezing it dry” is (in fractions) _____g; Method 2: Use 3,700g of clean water to evenly divide into three equal parts (1900g each). Three times rinsing; the first time, rinsing with 1900g of clean water, remaining on clothes after wringing
