(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1怎么解啊!
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1怎么解啊!
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1怎么解啊!
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1
1/4*(6-x)+3/20*x=1
3/2-1/4*x+3/20*x=1
(1/4-3/20)x=3/2-1
1/10*x=1/2
x=1/2÷1/10
x=5
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1
1/4*(6-x)+3/20*x=1
5(6-x)+3x=20
x=5
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1
1/4*(6-x)+3/20*x=1
同时乘20,得:
5(6-x)+3x=20
30-5x+3x=20
30-2x=20
2x=30-20
2x=10
x=5
[1/10+(1/12+1/15)]*(6-x)+(1/12+1/15)*x=1
1/10*(6-x)+(1/12+1/15)*(6-x)+(1/12+1/15)*x=1
1/10*(6-x)+(1/12+1/15)*6-(1/12+1/15)*x+(1/12+1/15)*x=1
1/10*(6-x)+(1/12+1/15)*6=1
下面就好算了
x=5
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1怎么解啊!
(1/10+1/12+1/15)*(6-x)+(1/12+1/15)*x=1怎么解有分加

1/12+1/15+1/10
1/6:X=15/12:3/10X*3/10=15/12*1/6为什么要这么做X*1/6=3/10*15/12
(1/2+1/4+1/6+1/10+1/12+1/60)/(1+1/3+1/5+1/10+1/15+1/30)
1/3+1/6+1/9+1/12+1/15
1/4:1/5:1/6=15:12:10怎么得来的,1/5:1/6=15:12:10
(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
1,3,6,10,15,< >
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)快
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)=
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)怎么解?
(1/2+1/4+1/6+1/8)-(1/3+1/6+1/9+1/12)+(1/4+1/8+1/12+1/16)-(1/5+1/10+1/15+1/20)
1÷(1/10+1/15+1/12)
(7/12-15/15)/1又6分之1
