最后一到列式计算
-1与-5/12的差再减去-1/6与-5/8的和所得到的差是多少?
我最多给1个小时的时间!

(-1)/((12)*(-8分之5)+3*(-0.5))(-4)/(-6)
1/8×(x+0.5)=3/4
简便运算 1-(0.5-2/3)÷1/3×[-2-(-9)]-1/8
-8×(+12)×(-7)÷13 -14+(1-0.5)*三分之一*(3-9)
√8+(√3+1)(√3-1)-√0.5
加上适当的运算符号和括号,使等式左右两边相等.(1)0.5 0.5 0.5 0.5 0.5=0(2)0.5 0.5 0.5 0.5 0.5=0.5(3)0.5 0.5 0.5 0.5 0.5=1(4)0.5 0.5 0.5 0.5 0.5=1.5(5)0.5 0.5 0.5 0.5 0.5=2.5
1-8(1/4+0.5x)=3(1-2x)
1-8(4分之1+0.5x)=3(1-2x)
1-8(1/4+0.5x)=3(1-2x)
(8/3-0.125)除以0.5=?
0.5,1,0.5,2,(),():括号里应该填什么数字啊?为什么?还有:1,3,8,15,26,()?
17、(1/2-1/3)2×8 18、-23-(1+0.5)×1/3÷(-2)
1-(0.5-4/9)*3*{-2-(-27)}-|1/8-0.25|
(根号18-根号0.5+2根号1/3)-(根号1/8-根号 12)
(根号0.5减2倍根号1/3)减(1/8减根号75)
(根号32+根号0.5-2根号1/3)-(根号1/8-根号48)
(√0.5-2√1/3+√32)-(√75+√1/8)
