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%=
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
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
