1.=18/0.76=1800/76=450/19=437又13/19
2.=-1
3.-3-(10.5*(-5))=49.5
18÷【1-(0.4+(1-0.4)】×0.4 等于多少?18÷【1-(0.4+(1-0.4)】×0.4
18÷{1-{0.4+(1-0.4)}*0.4= 1÷(6/1-3/1)*6/1= -3-{4-(4-3.5*3/1)}*{-2+(-3)}=急
11/2÷ 0.4=1.35÷ x;12+3(x-1)=18;5x+1=3+3(1-x);x÷ 48=24÷ 32;x÷ 2.6=2.88÷ 15.6
12.5÷0.4=31.0.1对吗
[(6.1-4.6)0.8-1]÷0.4
18除以{1减【0.4加【1减0.4】】乘0.4}
(-36)÷(-2) 3/7÷(-6/7) 0÷0.4 (-6)÷(-6/1)
-1-{(-3)²-[3+0.4×(-1又½)]÷(-2)}的得数等于多少- 1 - { ( - 3 )² - [ 3 + 0.4×(1½)]÷(-2)﹜
(3.12+0.3)÷〔(1-0.4)÷0.2〕巧算 有急用!
-1-{(-3)2-〔3+0.4×(-1 1/2)〕÷(-2)}
-1-{(-3)^2-[3+0.4×(-1/1/2)]÷(-2)}
解方程!快! 11/2÷ 0.4=1.35÷ x;12+3(x-1)=18;5x+1=3+3(1-x);x÷ 48=24÷ 32;
(4分之1+0.75)÷(2又2分之1×0.4+1又5分之4÷1.8) )
(能简算的要用简便方法计算) 1÷2.5+2.5*0.4+1简便
[(6.1-4.6)÷0.8-1]×0.4可以简便就简便计算(递等式)
[(6.1-4.6)÷0.8-1]×0.4可以简便就简便计算(递等式)
(8分之7-0.4)÷(4分之1+10分之3)
(-1-1/17)²×17/18+(-99又2/3)×24-1-{(-3)³-[3+0.4×(-1又1/5)]÷(-2)}半小时内求答案!蟹蟹哟...
