因为11/111=12221/123321
111/1111=12321/123321
所以11/111小于111/1111
祝你学业进步
1-11/111=100/111
1-111/1111=1000/1111
100*10/111*10=1000/1110
因为1000/1110大于1000/1111
所以11/111小于1000/1111
做比法
11/111÷111/1111
=11/111×1111/111
=11/1111<1
所以11/111<111/1111
11/111-111/1111=(11*1111-111*111)/(111*1111)
=[(10+1)(1000+1)-(100+1)(100+1)]/(111*111)
=(10000+1000+10+1-10000-200-1)/(111*111)
=810/(111*111)>0
故:11/111>111/1111
11/111-111/1111
=(11*1111-111*111)/111*1111
=(12221-12321)/111*1111
=-100/111*1111
<0
11/111<111/1111
