9又9/16÷9
＝(9＋9/16)÷9
＝9÷9＋9/16÷9
＝1＋1/16
＝17/16

(90+1/88)×1/89
＝(90×88＋1)/88×1/89
＝[(89+1)×(89-1)＋1]/88×1/89
＝[89^2－1^2＋1]/88×1/89
＝89^2/88×1/89
＝89/88

(1/3-1/4)+(1/4-1/5)+(1/5-1/6)
＝1/3-1/4+1/4-1/5+1/5-1/6

＝5/4×2
＝2.5

9又2000/2001×1949
＝(10-1/2001)×1949
＝10×1949－1/2001×1949
＝19490－1949/2001
＝10489＋(1-1949/2001)
＝10489＋52/2001
＝10489又52/2001

好、、好、、、多。。。。
光看就够头疼。。

但是咬咬咬牙还是给楼主算一下。。
orz..楼住以后能不能不用空格 2题很容易看成1题

125/（50/8）
=125*8/50
=1000/50
=
7.2*102
=7.2*(100+2)
=7.2*100+14.4
=720+14.4
=

9又9/16÷9
=(9+9/16)*1/9
=9*1/9+9/16*1/9
=

Answer 4

125÷(50÷8) =125*8/50
7.2×1.02 =7.2X1+7.2*0.02
9又9/16÷9 =9*1/9+(9/16)*(1/9)

(90+1/88)×1/89 =89*(1/89)+(89/88)*(1/89)

(1/3-1/4)+(1/4-1/5)+(1/5-1/6) =1/3-1/4+1/4-1/5+1/5-1/6=1/3-1/6
