同学们想知道在中考中如何考查有理数吗?让我们一起走进辛老师的课堂吧.一、数形结合例1(2013年菏泽)如图1,数轴(不完整)上的A、B、C三点所表示的数分别为a、b、c,其中AB=BC.如果|a|>|b|>|c|,那么该数轴的原点0的位置应该在().A.点A的左边B.点A与点B之间C.点B与点C之间D.点B与点C之间或点C的右边解析:根据绝对值的定义解题.在数轴上,表示一个数的点到原点的距离叫作这个数的绝对值.由|a|>|b|>|c|知:点A到原点的距离>点 Students would like to know how to test the rational numbers in the senior high school entrance examination? Let us enter the class of Xin teacher together. First, the combination of example 1 (Heze 2013) Figure 1, the number of axes (incomplete) on the A, B, A, b, c, where AB = BC. If | a |> | b |> | c |, then the origin 0 of the number axis should be at () .A. Point A On the left B. Between point A and point B C. Between point B and point C D. Between point B and point C or right of point C Resolution: According to the definition of the absolute value of the problem. On the axis, said a number The distance from the origin to the origin is called the absolute value of this number. By | a |> | b |> | c |
