0.888*0.8+0.111*3.6
=(0.888/8)*(0.8*8)+0.111*3.6
=0.111*3.6+0.111*3.6
=0.111*(3.6+3.6)
=0.111*7.2
=0.7992
=(0.888/8)*(0.8*8)+0.111*3.6
=0.111*3.6+0.111*3.6
=0.111*(3.6+3.6)
=0.111*7.2
=0.7992

0.888×0.88+0.111×3.6
=0.111×8×0.88+0.111×3.6
=0.111×﹙8×0.88+3.6﹚
=0.111 ×﹙7.04+3.6﹚
=0.111×10.64
=0.111×8×0.88+0.111×3.6
=0.111×﹙8×0.88+3.6﹚
=0.111 ×﹙7.04+3.6﹚
=0.111×10.64

=8*0.8*0.111+0.111*3.6
=6.4*0.111+0.111*3.6
=(6.4+3.6)*0.111
=10*.111
=1.11
把0.888分成了8个0.111。
