(3.6*0.75*1.2) (1*2.4*0.18)怎样简便运算
(先化简再求比值)1.2比0.75

1.2比0.75=5分之6比4分之3=5分之6乘以3分之4=5分之8=8比5=1.6

简算 1.(3.6*0.75*1.2)/(1.5*24*0.18)

(3.6*0.75*1.2)/(1.5*24*0.18)=(0.9*4*0.25*3*3*0.4)/(3*0.25*2*0.2*0.9)上下约去,0.930.25=(4*3*0.4)/(2*0.2)=

1÷0.25+0.75 5.3*3.6+3.6*4.7简便计算

3.6*11.1+1.2*66.7=?简便算

3.6*11.1+1.2*66.7=1.2*33.3+1.2*66.7=1.2*(33.3+66.7)=1.2*100=120

简便3.6×88+36×1.2

3.6×88+36×1.2=3.6×88+3.6×12=3.6×(88+12)=3.6×100=360再问:还有呢?再答:不回答追问里的新问题,请采纳了再提问,谢谢!

1.2除以0.75加7.2除以24

1.2*4/3+7.2/24=1.6+0.3=1.9

3.6/0.4-1.2*5怎么简算

=(9*0.4)/0.4-(0.6*2)*5=9-0.6*(2*5)=9-6=3

3.6*0.75/3.6*0.75简便计算

3.6*0.75/3.6*0.75=3.6/3.6*0.75*0.75=3/4*3/4=9/16

(3.6×0.75×1.2)÷(1.5×24×0.18)

(3.6×0.75×1.2)÷(1.5×24×0.18),=(2.7×1.2)÷(36×0.18),=3.24÷6.48,=0.5.

3.6除以0.75的竖式

150|4600450----------------100

简便计算:3.6÷0.75+0.75

直接算最简单等于5.55

3.6*0.75+3.6/4如何简便计算

3.6*0.75+3.6/4=3.6*0.75+3.6*0.25=3.6*(0.75+0.25)=3.6*1=3.6

1.2/0.75+0.8如何简便方法计算

1.2/0.75+0.8=1.2×4/3+0.8=1.6+0.8=2.4

(-1.2)×0.75×(-1.25)的计算过程

(-1.2)×0.75×(-1.25)=6/5×3/4×5/4=6/5×5/4×3/4=3/2×3/4=9/8

巧算3.6×11.1+1.2×66.7

3×1.2×11.1+1.2×66.7=1.2×33.3+1.2×66.7=1.2×(33.3+66.7)=120

1.2.6+2X=3.6

1,.2x=3.6-2.62.4(x-2.2)=38*33.9x-4x=68.5-53x=10/2x-2.2=114/45x=15.5x=5x=28.5+2.2x=3.1x=30.7

简算(3.6*0.75*1.2)/(1.5*2.4*0.18)

由题意得原式=3.6÷0.18×0.75÷1.5×1.2÷2.4=20×0.5×0.5=5

90/(3.6-1.8) 3.6/0.4-1.2*5
