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% 看不太懂題意...@@ 還煩請提點一下,謝謝 另外順便請教一下有關餘數的定義 2除以4的餘數是算2還是0呢? 因為有點搞不清除盡與整除的餘數分別 感謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.229.17.70
