1三桶分油问题概述《轻巧夺冠优化训练.三年级数学(上)(北师大版)》[1]有一道动脑筋题:有A、B、C三个油桶,A桶可装12千克油,B桶可装8千克油,C桶可装5千克油,现有12千克油全部装在A桶中,要将它分成两个6千克油,请问该如何来倒?该题实质是,没有可计量的量器,只有三个不规则的油桶,已知每个桶的容积,通过将油在三个桶之间倒来倒去,把最大桶的满桶油均分为两等
Three barrel oil problem summary “Lightweight champion optimization training. The third grade mathematics (on) (Beijing Normal University Edition)” [1] There is a moving brain problem: A, B, C three drums, A barrel can be installed 12 kg of oil, B barrel can hold 8 kg of oil, C barrel can hold 5 kg of oil, the existing 12 kg of oil are all packed in A barrel, it is divided into two 6 kg oil, how to pour? The essence is that there are no measurable gauges, only three irregular buckets, the volume of each bucket being known, the maximum buckets of oil being equally divided by pouring the oil between the three buckets For two and so on
