0.6×1/9+3/5×1又5/9-0.16*75%简算求过程
0.6×1/9+3/5×1又5/9-0.16*75%简算求过程

0.6×1/9+3/5×1又5/9-0.16*75%简算求过程
0.6×1/9+3/5×1又5/9-0.16*75%
=0.6×(1/9+1又5/9)-0.16×3/4
=0.6×1又2/3-0.12
=1-0.12
=0.88

0.6×1/9+3/5×1又5/9-0.16*75%
=0.6×1/9+0.9×14/9-0.16*3/4
=0.6×（1/9+14/9)-0.12
=0.6×5/3-0.12
=1-0.12
=0.88

=0.6(1/9+1+5/9-0.8*25%)=0.6(1+2/3-2/5)=19/25
