2/3÷5/7 7/5×1/3简算 除3余1除5余2除7余3

现在看官们对于2/3÷5/7 7/5×1/3简算事件始末原因揭秘，看官们都想要分析一下2/3÷5/7 7/5×1/3简算，那么语琴也在网络上收集了一些对于除3余1除5余2除7余3的一些信息来分享给看官们，是什么原因呢？，看官们一起来简单了解下吧。

简便计算过程如下 5/7-2/3-1/3 =5/7-(2/3+1/3) =5/7-3/3 =5/7-1 =5/7-7/7 =-2/7 望采纳

解:du2/5减zhi1/3乘5/7加dao2/3除以1/3=2/5-1/3x5/7+2/3x3=2/5-1/3x5/7+2=12/5-5/21=252/105-25/105=(回252-25)答/1.

2/3+1/3*1/5 =1/3(2+1/5)=1/3*11/5=11/15

展开全部 [7/5÷(5/7*2/3)]÷6/7 =7/5÷5/7÷2/3÷6/7 =(7/5*7/5)*(3/2*7/6) =49/25*7/4 =343/100 =3.43

2/1*3+2/3*5+2/5*7+2/7*9+……+2/97*99 =(3-1)/1*3+(5-3)/3*5+(7-5)/5*7+……+(99-97)/97*99 =1-1/3+1/3-1/5+1/.

2/3÷(0.5*1/3) =2/3÷[(1/2)*1/3] =2/3÷1/6 =2/3*6 =4

=(2/3+1/3)*8/5 =8/5

(3/4-2/3)÷1/5 =1/12ch35 =5/12 4/5*7/8+7/8÷5 =(4/5+1/50*7/8 =1*7/8 =7/8 (1-8/15*3/4)÷3/5 =(1-2/5)*5/3 =3/5*5/3 =1 (3/8+2/17)*8+1/17 =3/8*8+(16/17+1/17) =3+1 =4
