(1)1/3--1/6=1/6
(2)1--3/10=7/10
(3)1/12+1/4=1/3
(4)5/21+2/7=11/21
(5)19/35--1/5=12/35
(6)3/10+?/12
所以 (1)、(4)的答数大于1/2,(1)、(3)、(5)的答数小于1/2.

计算:1/6-(+1/3)-(-1/12)
1/3*2/5+1/6*1/5+1/12*3/10
(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+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+1/3+1/6+1/10+...+1/5050越快越好,
1/3+1/6+1/10+1/5+.+1/5050
1/3+1/6+1/10+1/5+.+1/5050
8/5:4/1、4/3:10/1,12/1:6/1化简.
(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+12+3+45+6
1/2+1/3+1/4+1/5+1/6+1/7+1/8+1/9+1/10+1/11+1/12的整数部分是几,为啥
