时间Tue May 29 22:49:31 2007
By weight, liquid A makes up 7.0% of solution I and 14.5% of suloution II.
If 3 grams of solution I is mixed with 2 grams of solution II,
then liquidA accounts for what percent of the weight of the resulting solution?
Ans: 10%
看不太懂题意...@@
还烦请提点一下，谢谢
另外顺便请教一下有关余数的定义
２除以４的余数是算２还是０呢？
因为有点搞不清除尽与整除的余数分别
感谢
