行测资料分析中的百分数化为分数
1.常用百分数化分数 50% = 1/2 , 33% = 1/3 , 20% = 1/5, 10% = 1/10;2.百分数整数部分(7-12)和分母的和为20 12.5% = 1/8 , 11.1% = 1/9 , 8.3% = 1/12, 7.7% = 1/133.(16,6)和(14,7)两对互换 16.7% = 1/6 , 6.25% = 1/16, 14.3% = 1/7 , 7

基期:被用来做对比的量现期:现在的量同比:与上一年同一时期做比较环比:与它紧挨着的上一周期做比较百分数与百分点:增长率与倍数:成数与翻番:增幅、降幅与变化幅度:增长率(增速,增幅,增值率)= (现期-基期)/基期增幅比较(增长率):高减低加降幅比较(增长率):-(高减低加)--->前面加负号,负的高减低加
