比,既可以表示两个相同量之间的除法关系,也可以表示两个不同量之间的除法关系,比在小学数学中有着广泛的应用,在圆柱、圆锥这部分内容中运用得当,非常有助于解决问题。例1甲、乙两个圆柱容器高度相同,已知底面半径分别为4厘米、2厘米,甲容器中水深10厘米,乙容器中水深4厘米,如果把甲容器中倒出一些水给乙容器直到两个容器中水面高度相平,问现在两个容器中水面高度是多少厘米?这道题可用常规方法去解,列式为:
Ratio, can not only represent the division between two the same amount, but also can be expressed as the division between two different quantities than in primary school mathematics has a wide range of applications, in the cylindrical, conical this part of the contents of the use of appropriate, very Help solve the problem. Example 1 A, B two cylindrical containers of the same height, known as the bottom radius of 4 cm, 2 cm, a container of water depth of 10 cm, B container water depth of 4 cm, if the container A pour some water to the container Until the two containers in the water level of the same phase, and asked now two containers in the water height is how many centimeters? The problem can be solved by conventional methods, the formula is:
