34除35乘36=34/35×(35+1)=34+34/35=34又34/35
=11.7*57*85/1.7/1.9/13/5/3=11.7*57*50/1.9/13/5/3=11.7*19*10/1.9/13=11.7/13*100=90
=0.04*25*(1.38/0.46)=1*3=3
8.35乘101减8.35=8.35×(101-1)=8.35×100=8350.8乘(3.2减2.99÷3.2)=0.8×3.2-0.8×2.99÷3.2=2.56-2.99÷(3.2÷0.8)=2
(38乘56乘64)除(19乘28乘16)=38/19*56/28*64/16=2*2*4=16
8.71乘3.64除1.82怎样简便运算?8.71×3.64÷1.82=8.71×(3.64÷1.82)=8.71×2=17.422.5.1除0.25除1.7怎样简便运算?5.1÷0.25÷1.7=5
125*8/(25*4)=125*4*2/(100)=600*2/100=6*2=12完毕,请打分
第一式是除以,不是除吧.如果是除,方法类似.6÷0.25÷0.4=6÷1/4÷2/5=6*4*5/2=600.25*(17.3+30.7)=1/4*48=12
378除378除265乘265乘194除194?
(425×5775+4225×425)÷125÷8=425×(5775+4225)÷(125×8)=425×10000÷1000=425×(10000÷1000)=425×10=4250
5.75加4.25乘2加78=5.75+8.5+78=14.25+78=92.250.75乘18÷0.15减6.8=0.75÷0.15×18-6.8=5×18-6.8=90-6.8=83.4
先把两个36除掉,然后36乘以25
你好!123×456÷789÷456×789÷123=123÷123×456÷456×789÷789=1再问:太谢谢了再答:助人为乐
=(36+1)×5/36=36×5/36+1×5/36=5+5/36=5又36分之5
98+98乘98+98=98*(1+98+1)=98*100=980032乘25除125=32*25*8/(125*8)=64*25*4/1000=64*100/1000=6.4
1991*1992*100010001-1992*1991*100010001=0;(91/13)*(75/25)*(45/16)=7*3*45/16=945/16
1.9-1.9*0.9=1.9*(1-0.9)=1.9*0.1=0.195.4除(3.94+0.86)乘0.8=5.4÷(4.8)*0.8=54÷6=9
寒樱暖暖为你8.1÷(0.9×0.3)=8.1÷0.9÷0.3=90÷0.3=300(或在客户端右上角评价点【满意】)是我前进的动力!你的采纳也会给你带去财富值的.如有不明白,直到完成弄懂此题!
20%=0.21.65÷5+1.29×0.2+3/50×0.2=1.65×0.2+1.29×0.2+0.06×0.2=(1.65+1.29+0.06)×0.2=3×0.2=0.6
