结果是1乘除法则是可以移项换项结果不变的,换了之后就是4.27÷4.27*26.8÷2.68*3.59÷35.9前面两项结果是1,中间是1,后面也是1,最后相乘就是1
0.865*51%+51*35.5%/2*1/50+4.9%*12又1/5=0.865*51%+51%*0.355+4.9%*61/5=(0.865+0.355)*51%+4.9%*61/5=1.22
再答:又是我哦
4.9÷1.4=(4.9÷0.7)÷2=7÷2=3.53.9÷(1.3×5)=(3.9÷1.3)÷5=3÷5=0.6
8又5/6+2.75+2又1/6+7又1/4=8又5/6+2又1/6+2又3/4+7.25=11+10=214.9x5又1/2+4.9+3又1/2x4.9=4.9(5又1/2+3又1/2+1)=4.9
4.89+12.11-7.73=17-7.73=9.27
4.89×9.9+4.89÷10=4.89x9.9+4.89x0.1=4.89x(9.9+0.1)=4.89x10=48.93.65÷0.25+6.35×4=3.65x4+6.35x4=(3.65+6
0.49[1/(4.9-4.89)]+6=0.49÷0.1+6=0.49+6=6.4938.2*7.5+75+0.75*518=0.75×(382+518)=0.75×900=675
=4.9乘以(4.9+1)
(4.8+4.9*2+5)*25=(9.8+9.8)*25=9.8*2*25=9.8*50=490
不太好说,要看具体震型,一般按如下分级参考:1级:无感-仅仪器能记录到;2级:微有感-特别敏感的人在完全静止中有感;3级:少有感-室内少数人在静止中有感,悬挂物轻微摆动;4级:多有感-室内大多数人,室
1.25×(0.8+0.4)=1.25×0.8+1.25×0.4=1+0.5=1.54.89×99+4.89=4.89×(99+1)=489(14.7+5.6)÷7=14.7÷7+5.6÷7=2.1+
全部化成分数再进行运算=(55/100-20/100)/(5/7×49/10)=35/100/7/2=1/10
2.8×23.4+35.9×7.2=(10-7.2)×23.4+35.9×7.2=10×23.4-7.2×23.4+35.9×7.2=234+(-23.4+35.9)×7.2=234+12.5×7.2
15/16+(8/9-2/3)*1/2=15/16+4/9-1/3=15/16+4/9-3/9=15/16+1/9=(135+16)/144=151/144720/12/5=720×5/12=60×5
(4.8+4.9+5+4.9+5)/5*10=0.492米
5X-(4.9-0.5*4.9)=1.655X-2.45=1.655X=4.1X=0.82
0.48×97+0.48×2+4.89÷10=0.48×97+0.48×2+0.48+0.009=0.48x(97+2+1)+0.009=0.48x100+0.009=48.009再问:0.48×97
一.9.8*4.5=(10-0.2)*4.5=45-0.9=44.1二.2.4*2.5*3.7=0.4*6*0.5*5*3.7=(0.4*0.5)*(6*5)*3.7=0.2*30*3.7=6*3.7
