3.6*0.75*1.2 (1.5*24*0.18)奥数怎么做
(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.(5.75-4.75)/[2.5+(0.75*1.25*8) 2.(6.9*3.6*3.5)/(1.25/0.25)

1、.(5.75-4.75)/[2.5+(0.75*1.25*8)=4/[2.5+(0.75*10)]=4/(2.5+7.5)=4/10=0.42、(6.9*3.6*3.5)/(1.25/0.25)=

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

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*0.75/3.6*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

+0.75+-2.8+-0.2-1.

(+0.75)+(-2.8)+(-0.2)-1.25=0.75-1.25-(0.28+0.2)=-0.5-0.3=-0.8不懂的欢迎追问,

3.6乘以1.

3.6的6/5是多少?3.6的120%是多少?

(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

0.75分之x=1.x分之25=1.2分之75

x/0.75=2/1.25==>1.25x=0.75*2==>1.25x=1.5==>x=1.5/1.25==>x=1.225/x=75/1.2==>75x=25*1.2==>75x=30==>x=0

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

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

你都会上百度问就不会用计算器么?开始-》附件-》计算器.
