0.5+(-1)/4-(-2.75)+1/2 = 3.5 (-2/3)+(-1/6)-(-1/4)-1/2 =.第二题求过程和结果
0.5+(-1)/4-(-2.75)+1/2 = 3.5 (-2/3)+(-1/6)-(-1/4)-1/2 =.第二题求过程和结果
0.5+(-1)/4-(-2.75)+1/2 = 3.5 (-2/3)+(-1/6)-(-1/4)-1/2 =.第二题求过程和结果
0.5+(-1)/4-(-2.75)+1/2
=(0.5+0.5)+(2.75-0.25)
=1+2.5
=3.5
(-2/3)+(-1/6)-(-1/4)-1/2
=-2/3-1/6+1/4-1/2
=-8/12-2/12+3/14-6/12
=-13/12
如果本题有什么不明白可以追问,
0.5+(-1)/4-(-2.75)+1/2
=0.5-0.25+2.75+0.5
=0.25+3.25
= 3.5
(-2/3)+(-1/6)-(-1/4)-1/2
=-8/12-2/12+3/12-6/12
=-14/12+3/12
=-11/12
0.5+【-4分之1】-【-2.75】+2分之1
0.5 (-1/4)-(-2.75) 1/2怎么算
计算:-0.5-(-3 1/4)+2.75-7 1/2
计算:0.5-(-3又4分之1)+(1+2.75)-(+5又2分之1)
0.5+(-4又1/4)-(+2.75)-(-6又1/2) 我要算式啊
负0.5减负3又4分之1加2.75减7又2分之1
(-0.5)-(-3又4分之1)+2.75-(+7又2分之1)
(-0.5)+3又4分之1+2.75+(-5又2分之1)
﹙﹣0.5﹚-[﹣3又4分之1]+2.75-[7又2分之1]
﹣0.5-3又4分之1+(﹣2.75)+7又2分之1
(-0.5)+3又4分之1+2.75+(5又2分之1)怎么做
(负0.5)+3又4分之1+2.75+(负7又2分之1)
(负0.5)-(负3又4分之1)+2.75-(正7又2分之1)
-0.5-(-3又4分子1)+2.75-+7又2分之1
(﹣0.5)+(+3又4分之1)+(+2.75)+(﹣5又2分之1)
有理数加减法运算-0.5-(-3 1/4)+2.75-(+7 1/2)怎么解?
(-5 右2分之1)-(-2.75)+3 右4分之1+(-0.5)=?
