Answer 1

解：3.6×0.57+0.64×5.7
=3.6×0.57+0.64×（0.57×10）
=3.6×0.57+0.64×0.57×10
=0.57×（3.6+0.64×10）
=0.57×10
=5.7

Answer 2

3.6×0.57+0.64×5.7
＝3.6×0.57+6.4×0.57
＝（3.6+6.4）×0.57
＝1×0.57
＝0.57

Answer 3

3.6×0.57+0.64×5.7=3.6×0.57+6.6×0.57=0.57×(3.6+6.6)=0.57×10=5.7

Answer 4

这道题的简便计算具体过程如下：
3.6x0.57+0.64x5.7
＝3.6x0.57+6.4x0.57
＝（3.6+6.4）x0.57
＝10x0.57
＝5.7

Answer 5

3.6×0.57+0.64×5.7这样简算：
3.6×0.57+0.64×5.7=0.36×5.7+0.64×5.7
=5.7×(0.36+0.64)
=5.7×1
=5.7
