1/2+1/4+1/6+1/8+1/16+1/32=?
1/2+1/4+1/6+1/8+1/16+1/32=?

1/2+1/4+1/6+1/8+1/16+1/32=?
1/2+1/4+1/6+1/8+1/16+1/32
=1/2+1/4+1/8+1/16+1/32+1/32-1/32+1/6
=1-1/32+1/6=109/96

1/2+1/4+1/6+1/8+1/16+1/32
=(1/2)(1+1/2+1/3+1/4+1/16)
=(1/2)(48/48+24/48+16/48+12/48+3/48)
=(1/96)(48+24+16+12+3)
=103/96

1/2+1/4+1/6+1/8+1/16+1/32 题错了吧
