Question

小学数学，六年级，求解，要详细过程，谢谢

Answer 1

1/5*1/6 = 1/5 - 1/6
1/7*1/8 = 1/7 - 1/8
可以化简为
1/5-1/6 +1/6-1/7 + 1/7-1/8 + 1/8-1/9 +1/9-1/10
= 1/5 -1/10
= 1/10

Answer 2

运用反通分法.
解:原式=(1/5-1/6)+(1/6-1/7)+(1/7-1/8)+(1/8-1/9)+(1/9-1/10)
=1/5-1/10
=1/10

Answer 3

通过找规律得：
1/5*1/6=1/5-1/6
所以原式=1/5-1/6+1/6-1/7......+1/9-1/10
=1/5-1/10
=1/10

Answer 4

你用计算机把分母相乘再相加就行

Answer 5

=1/5-1/6+1/6-1/7+1/7-1/8+1/8-1/9+1/9-1/10
=1/5-1/10
=1/10
