下面各题,该怎样简便就怎样计算: 95.6×8+0.4÷0.125= 100.65-45.63+9.35-14.37=8/9×[3/4-﹙7/16-0.25)=6.25×3/5+2.75÷1又2/3+60%=
95.6×8+0.4÷0.125=95.6×8+0.4×8=(95.6+0.4)×8=100×8=800
100.65-45.63+9.35-14.37=(100.65+9.35)-(45.63+14.37)=110-60=50
8/9×[3/4-﹙7/16-0.25)=8/9×[3/4-7/16+1/4]=8/9×(1-7/16)=8/9×(9/16)=1/2
6.25×3/5+2.75÷1又2/3+60%=6.25×3/5+2.75×3/5+3/5=3/5×(6.25+2.75+1)=3/5×10=6

1、95.6×8+0.4÷0.125

=95.6×8+0.4×8

=(95.6+0.4)×8

=100×8

=800

2、 100.65-45.63+9.35-14.37

=(100.65+9.35)-(45.63+14.37)

=110-60

=50

3、 8/9×[3/4-﹙7/16-0.25)]

=8/9×(3/4-7/16+1/4)

=8/9×(1-7/16)

=8/9×9/16

=1/2
