Question

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％=

Answer 1

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

Answer 2

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
