proportion强调比例,比如什么东西在什么中占的比例很大percentage 指百分比 将一般的比值化成百分数rate 指比率 比如利率什么的ratio 指比例 是指A在一个整体中所占的比例

ratio:一般是指两个数字的比例例子：水与面粉的比例是1：2; 1杯水：两杯面粉proportion:是指A part considered in relation to the whole,一块皮萨是一整个皮萨的八分之一：1/8rate:A quantity measured with respect to anoth 一个单位比另一个单位：每小时六十公里：60km/hrpercentage:百分比:90% (很多时候,porportion就是用percentage来表达的）scale:A standard of mea 最简单的说法就是比如你看一张地图的时候,地图上会有一个小标志指明一英寸代表1公立,这里的scale就是说一英寸就是着这样地图的“单位”,整张地图就是按照这个单位来用的.
