Look at Xiaoli's first:
There was 1kg of sewage in the clothes, plus 10kg of clean water, a * * had 1 1kg of water, of which sewage accounted for11,which was/kloc.
After wringing, there is 1kg of water in the clothes. Because the ratio of sewage to water remains unchanged, the remaining sewage in the clothes is1x11=11.
Xiao Ju:
The original sewage in the clothes is 1kg. Add 3kg of clean water first, and one * * * has 4kg of water, of which sewage accounts for 1/4, which is 1kg.
There is 1kg water in the clothes after wringing. Because the ratio of sewage to water remains unchanged, the remaining sewage in clothes is1x1/4 =1/4 kg.
Add 7 kilograms of clean water to clothes, and there are 8 kilograms of water, including sewage 1/4 kilograms, accounting for (1/4)÷8= 1/32 of the total water.
There is 1kg water in the clothes after wringing. Because the ratio of sewage to water remains unchanged, the remaining sewage in clothes is1x1/32 =1/32kg.
1/ 1 1 & gt； 1/32
So Xiao Ju washes more cleanly.
