比较分数大小问题是初中数学竞赛的一 类常见问题,现介绍几种常用解法,以供同学们 学习参考． 一、巧加数字 例1 (1992年第九届“缙云杯”初中数学 邀请赛试题)把-1991/1992,-91/92,-1992/1993,-92/93四 个分数从小到大排列是____． 解:将每个分数都加上1,可得: 比较分数大小问题是初中数学竞赛的一 类常见问题,现介绍几种常用解法,以供同学们 学习参考． 一、巧加数字 例1 (1992年第九届“缙云杯”初中数学 邀请赛试题)把-1991/1992,-91/92,-1992/1993,-92/93四 个分数从小到大排列是____． 解:将每个分数都加上1,可得:
The problem of comparing fractional scores is a common problem in junior high school math competitions. Now we introduce several common solutions for students to learn. First, the number of clever figures 1 (the 1992 “Jinyun Cup” junior high school mathematics invitational exam questions) arranged the four scores of -1991/1992, -91/92, -1992/1993, -92/93 from small to large ____. Solution: Add 1 to each score to get: The problem of comparing scores is a common problem in junior high school math competitions. Now we introduce several common solutions for students to learn.
