(-2/3)+(+0.25)+(-1/6)-(+1/2)这题怎么做
(-2/3)+(+0.25)+(-1/6)-(+1/2)这题怎么做
(-2/3)+(+0.25)+(-1/6)-(+1/2)这题怎么做
=-2/3+1/4-1/6-1/2
=-2/3-1/2+1/4-1/6
=-2+1/4-1/6
=-24/12+3/12-2/12
=(-24+3-2)/12
=-23/12
=-2/3+0.25-1/6-1/2
=-2/3+1/4-1/6-1/2
=-8/12+3/12-2/12-6/12
=(-8+3-2-6)/12
=-13/12
楼上最后应该是减去1/2
(-2/3)+(+0.25)+(-1/6)-(+1/2)
=-2/3-1/6+1/4+1/2
=-5/6+3/4
=-1/12
(-2/3)+(+0.25)+(-1/6)-(+1/2)
= -2/3-1/6 +1/4+1/2
= -4/6-1/6 + 1/4+2/4
= -5/6 + 3/4
= -10/12 + 9/12
= -1/12
(-2/3)+0.25-1/6-0.5
[-2/3]+[+0.25]+[-1/6]-[+1/2]=__?
初一数学计算(-2/3+0.25-1/6-1/2)-2/3+0.25-1/6-1/2==
7/2+9/4+(-1/3)-0.25+(-1/6)
简算,(3/1-0.25)/2/1+6/5
解方程2/3x+0.25x=1/6
初中计算(-2)^4/(-2 2/3)^2+(5 1/2)*(-1/6)-0.25
计算:-3^4+(-0.25)^100×4^100+(1/2-1/3)×6^2÷|-2|
1/2-(-0.25)-1/6=?
(-6)÷6/5-【(-3)的三次方-(1-0.25÷1/2)】×18
(2/3)^2*2/3除|-3|*1/3+(-0.25)^3除(1/2)^6 急.现在就要
简便计算:①-0.25-{-2分之1-[3分之1+(4分之1-6分之1)]}
-0.25—{-1/2—[-1/3+(1/4—1/6)]}=
(1)1/6:30% (2)2/3:3/8 (3)0.48:0.06 (4)0.25:1/6
计算-8+[-1/7-(-1/6-0.25×2/3)÷7/3]-(8+9)
(0.5+0.25+0.125)/(0.5*0.25*0.125)*7/18*9/2+1/6/131/3-15/4*16/5
2有3分之2+0.25-1有6分之1
(-2/3)+(+0.25)+(-1/6)-(+1/2)这题怎么做
