帮忙求解两道数学题！谢谢各位

uniqueness

1.下列哪个数和下面算出的最接近？

式子是0.1667乘0.8333乘0.3333除以0.2222乘0，6667乘0.1250

A2.00B2.40C2.43D2.50E3.43

我把上下约分出来大概是3点多，可答案给的是D。望各位大虾帮助

2.DATA SUFFICIENCY

Town T has20000 residents,60 percent of whom are female.what percent of the residents were born in Town T?

(1)The number of female residents who were born in town T is twice the number of male residents who were not born in Town T

(2)The number of female residents who were not born in Town T is twice the number of female residents who were born in Town T

3.If the successive tick marks shown on the number line above are equally spaced and if x and y are the numbers designating the end points of intervals as shown,what is the value of y?

1 x=0.5

2 y-x=三分之二

谢谢各位了！！！

首先，经粗略统计是3道数学题 ：）

1.我估计你的算式应该是  0.1667乘0.8333乘0.3333除以（0.2222乘0，6667乘0.1250）

＝（1/6 * 5/6 *1/3) / (2/9 *2/3 *1/8) ＝5/2

2.C

已知可推出F＝12000，M＝8000

根据条件2 ＝》FnotB=2FB,=>FB=1/3F=4000

再根据条件1＝》FB=2MnotB =>MnotB=2000 => MB=8000-2000=6000

=>total B= 100000

两个条件缺一不可

3.没图没法看

这两个条件加起来应该是够了，是不是全都充分就不知道了
