请采纳,谢谢

你好,很高兴为你解答 0.888x125X73+999×3简便计算 =0.111x8x125x73+111x27 =111x73+111x27 =111x(73+27) =11100 满意采纳哦!

怎么这么久了都没人帮忙看不下去了(0.8+0.08+0.008)x125x73+3000-3=100x73+10X73+1X73+3000-3=111x73+3000-3=7300+730+73+3000_3=10300+730+70=10300+800+11000

0.888*125*73+999*3 =111*8*0.125*73+111*9*3 =111*76+111*27 =111*(73+27) =11100

=0.111×8×125×73+111×9×3 =0.111×(8×125)×73+111×(9×3) =111×73+111×27 =111×(73+27) =111×100 =11100

=0.111X8X125X73+9X111X3 =111X73+111X27 =111X(73+27) =111X100 =11100

8分之100乘以0.888等于11.1

解:0.888x0.8+0.111x3.6 =0.111x8x0.8+0.111x3.6……把0.888分解成0.111x8 =0.111x(8x0.8)+0.111x3.6……运用乘法结合律:axbxc=ax(bxc) =0.111x6.4+0.111x3.6 =0.111x(6.4+3.6)……运用乘法分配律:(a+b)xc=axc+bxc =0.111x10 =1.11

0.888*125*73+999*3 =111*8*0.125*73+111*9*3 =111*76+111*27 =111*(73+27) =11100

0.888×3.5-0.444×3简便方法 =0.4444x(2x3.5-3) =0.4444x4 =1.776
