1-10*(1/12)/(1/30) 怎么算
1-10*(1/12)/(1/30) 怎么算
1-10*(1/12)/(1/30) 怎么算
1-10*(1/12)/(1/30)
=1-10*（1/12）*30
=1-300/12
=12/12-300/12
=-288/12
=-24
=1-5/6*1/30
1-1/36=35/36
=1-（2*5）*(1/12)/(1/30)
=1-1/6*1/6
=1-1/36
=35/36
1-10*(1/12)/(1/30) 怎么算
6x+10*(1/12-x)+11/30=1
(1/2+1/4+1/6+1/10+1/12+1/60)/(1+1/3+1/5+1/10+1/15+1/30)
1/2+1/6+1/10+1/12+1/20+1/30+1/42+.+1/2008*20091/2+1/6+1/10+1/12+1/20+1/30+1/42+.1/2008*2009=?要用简便方法计算
(1+1/3+1/5+1/10+1/15+1/30)/(1/2+1/4+1/6+1/12+1/20+1/60)(用简算)
(1+1/3+1/5+1/10+1/15+1/30)/(1/2+1/4+1/6+1/12+1/20+1/60)=?简便计算方法
(1+1/3+1/5+1/10+1/15+1/30)/(1/2+1/4+1/6+1/12+1/20+1/60)=?简算
12-6+6-6+7-1+5+1+1= 30-10+30-10-10+20=
4x+10=10X-1+6 怎移项
1+10-11+12-1?
y=(1+20％)x① 30(1-10％)y-30x=12②

-1/2-1/6-1/12-1/20-1/30-1/42-1/56-1/72-1/90-1/10的结果要有过程
简算.-1/2-1/6-1/12-1/20-1/30-1/42-1/56-1/72-1/90-1/10
1/2+1/6+1/12+1/20+1/30+1/42+1/56+1/72+1/90+1/10等于多少?
