数学简便运算：0.92×54+0.46×92
数学简便运算：0.92×54+0.46×92
数学简便运算：0.92×54+0.46×92
0.92×54+0.46×92
=0.92×54+0.92×46
=0.92×（54+46）
=0.92×100
=92
0.92×54+0.46×92
=0.92×54+46×0.92
=0.92×(54+46)
=0.92×100
=92
=0.92x54+0.46x100x0.92
=0.92x(54+46)
=0.92x100=92
0.92×54+46×0.92
=0.92×(54+46)
0.92×54+0.46×92=0.92(54+0.46*100)=92
