问题描述:
(1)3/1,150%,1,3/4,60%,( ),( ),( ),...
规律是:( )
(2)90%,1,4/5,110%,0.7,( ),( ),( ),...
规律是:( )
(3)3/20,( ),0.65,9/10,115%,( ),( ),( ),...
规律是:( )
后面三个括号分别填上小数,分数,百分数,第三题前面这个括号填上百分数.
答
(1)3/1,150%,1,3/4,60%,(0.5),(3/7),(37.5%),...规律是:(分子不变,分母加一)(2)90%,1,4/5,110%,0.7,(1.2),(3/5),(130%),...规律是:(分母不变,分子比前两个加一或减一如:9/10,10/10,8/10,11/10,7/...
