答案
11分之6-(14分之5-11分之5) =6/11+5/11-5/14=1-5/14=9/14
4.5×4又4分之3+4又4分之3+4又4分之3×4又2分之1
=4.75×(4.5+1+4.5)
=4.75×10
=47.5
把1999分之1,2999分之2,3999分之3,4999分之4按照从大到小的顺序排列起来
1/1999=1/(1000+999)
2/2999=2/(2000+999)=1/(1000+999/2)
3/3999=1/(1000+999/3)
4/4999=1/(1000+999/4)
所以4/999>3/3999>2/2999>1/1999
4.5×4又4分之3+4又4分之3+4又4分之3×4又2分之1
=4.75×(4.5+1+4.5)
=4.75×10
=47.5
把1999分之1,2999分之2,3999分之3,4999分之4按照从大到小的顺序排列起来
1/1999=1/(1000+999)
2/2999=2/(2000+999)=1/(1000+999/2)
3/3999=1/(1000+999/3)
4/4999=1/(1000+999/4)
所以4/999>3/3999>2/2999>1/1999
