(-2/3)×(+1又1/3)×(-1-1/4)怎么写?
(-2/3)×(+1又1/3)×(-1-1/4)怎么写?
(-2/3)×(+1又1/3)×(-1-1/4)怎么写?
分数间的乘方通常先算括号内的,把带分数化成假分数再计算
(-2/3)×(+1又1/3)×(-1-1/4)
=(-2/3)×(4/3)×(-5/4)
=(8/9) ×(5/4)
=10/9
(-2/3)×(+1又1/3)×(-1-1/4) =(2/3)×(4/3)×(5/4) =10/9=1又1/9
-14又2/3-11又2/15-(-12又2/3)-14+(-11又2/15)(-4又1/8)-|-1+2+0.125|-|-3又1/3|-(-6又1/7)+(-5又1/7)又怎么做
(1又2/3+2又3/4+~+7又8/9+8又9/10)除以(3又1/3+5又2/4+7又3/5+~+15又7/9+17又8/10
-12又2/3-(-5又1/2)+(-3又1/3)-2又1/4-12又2/3-(-5又1/2)+(-3又1/3)-2又1/4
[1又1/3减(0.2+1/3)*4.5]+13又1/2简算12又3/4-2又2/5*3又3/4/2又1/26.3/(2.6+5又1/3*1又8/7)
(-7又3/2)+(-3又3/1)+8又4分之一=(-3又二分之一)(-7又3/2)+(-3又3/1)+8又4分之一+(-3又二分之一)
(2又1/3-3又1/2+1又1/45)÷(-1又2/3)
(-2000又5/6)+(-1999又2/3)-(-4000又3/4)-(+1又1/2)
(-2005又5/6)+(-2004又2/3)+4010又2/3+(-1又1/2)
计算(-2012又5/6)+(-2011又2/3)+4024又2/3+(-1又1/2)
【5又1/3+(8.7-3又1/2×2又1/7)】/19又3/5
6又2/7+(12又1/3)-15-(+7又2/7)-(-12又1/3)
计算:(-4又1/4)-(+3又1/8)+(-4又7/8)-(-5又1/2)
计算:-(1又2/3-4又11/12)-(13又11/18+3又1/4)
(2012又5/6)-2013又2/3+(-5又1/2)-(-4020又3/4)
计算:(-15又2/3)+【13又2/3-|-4又2/15|+(-4又1/5)】
8又11/15÷[2又1/3+1又7/9×(4又3/4-1.15)]=?
计算,3又1/4+(-2又3/5)+5又3/4+(-8又2/5)
3又1/4+(-2又3/5)+5又3/4+(-8又2/5)要有过程
