0.9999×0.6+0.1111×4.6=(简便运算)
0.9999×0.6+0.1111×4.6=(简便运算)

0.9999×0.6+0.1111×4.6=(简便运算)
0.9999×0.6+0.1111×4.6
=(1-0.1111)×0.6+0.1111×(4+0.6)
=1×0.6+0.1111×4
=0.6+0.4444
=1.0444

原式=0.1111×5.4+0.1111×4.6=0.1111×(5.4+4.6)=0.1111×10=1.111

0.9999*0.6+0.1111*4.6=0.1111*9*0.6+0.1111*4.6=0.1111*(9*0.6+4.6)=0.1111*(5.4+4.6)=0.1111*10=1.111
