来源:学生作业帮助网 编辑:作业帮 时间:2024/11/11 07:11:24
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
(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)=

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
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*4/3+7.2/24=1.6+0.3=1.9
=(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=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),=(2.7×1.2)÷(36×0.18),=3.24÷6.48,=0.5.

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=1.2×4/3+0.8=1.6+0.8=2.4
(-1.2)×0.75×(-1.25)=6/5×3/4×5/4=6/5×5/4×3/4=3/2×3/4=9/8
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,.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
由题意得原式=3.6÷0.18×0.75÷1.5×1.2÷2.4=20×0.5×0.5=5
