求0.96×101 3.69×9+3.69 2.14×1.25×0.8 2.5×3.2的简便计算结合脱式运算
求0.96×101 3.69×9+3.69 2.14×1.25×0.8 2.5×3.2的简便计算结合脱式运算
0.96×101
=0.96×(100+1)
=0.96×100+0.96×1
=96.96
3.69×9+3.69
=3.69×(9+1)
=3.69×10
=36.9
2.14×1.25×0.8
=2.14×(1.25×0.8)
=2.14×1
=2.14
2.5×3.2
=2.5×4×0.8
=10×0.8
=8
0.96×101
=0.96×100+0.96
=96+0.96
=96.96
3.69×9+3.69
=3.69×10
=36.9
2.14×1.25×0.8
=2.14×1
=2.14
2.5×3.2
=2.5×0.4×8
=1×8
=8
0.96*(100+1)=96+0.96=96.96
3.69*(9+1)=36.9
2.14*(1.25*0.8)=2.14*1=2.14
2.5*(0.4*8)=1*8=8
