分数的意义是:把单位“1”平均分成若干份,表示这样的一份或几份的数,叫作分数。
遇到一个分数,需要弄清楚对应于这个分数,单位“1”是哪个量。“谁是几分之几相对应的量?”意思就是问对应于下面的分数,谁是单位“1”?
下面说的“整体1”就是“单位1”。
1、整体1是这块布料未裁剪时的数量;
2、整体1是花钱之前一共有的钱数;
3、整体1是计划修筑的路程数,包括已修的和未修的;
4、应理解为“体积比原来膨胀了……”,整体1是原来水的体积;
5、乙数是整体1;
6、女生是整体1。
前三小题中整体1是事物的总量,后三小题中整体1是相比较的对象。
附带说明,五分之三应写作3/5;十一分之一应写作1/11,以此类推。
