简便算法,6.8乘0.99+0.068简便算法,6.8乘0.99+0.068简便算法,6.8乘0.99+0.0686.8*0.99+0.068=6.8*(1-0.01)+0.068=6.8*1-6.8
简便算法,6.8乘0.99+0.068
简便算法,6.8乘0.99+0.068
简便算法,6.8乘0.99+0.068
6.8*0.99+0.068
=6.8*(1-0.01)+0.068
=6.8*1-6.8*0.01+0.068
=6.8-0.068+0.068
=6.8
6.8*(0.99+0.01)
=6.8*1
=6.8
0.068*(99+1)=6.8
=6.8 x(1-0.01)+6.8 x 0.01
=6.8(1-0.01+0.01)
=6.8
6.8*0.99+6.8*0.01=(0.99+0.01)*6.8=6.8
6.8×(1-0.01)+0.068
=6.8-6.8×0.01+0.068
=6.8-0.068+0.068
=6.8
6.8乘0.99+6.8乘0.01等于6.8乘1
