Question

5.6×0.45+0.56×4.1+0.056×14,简便运算怎么算？

Answer 1

5.6×0.45+0.56×4.1+0.056×14=5.6×0.45+5.6×0.41+5.6×0.14=5.6×（0.45+0.41+0.14）=5.6×1=5.6

Answer 2

先利用“积不变的规律”把其中一个因数统一，再利用“乘法分配律”进行简算
5.6×0.45+0.56×4.1+0.056×14
=5.6×0.45+5.6×0.41+5.6×0.14
=5.6×（0.45+0.41+0.14）
=5.6×1
=5.6

Answer 3

利用乘法结合律计算
原式=0.56×4.5+0.56×4.1+0.56×1.4
=0.56×（4.5+4.1+1.4）
=0.56×10=5.6

Answer 4

简便计算5.6×0.45+0.56×4.1+0.056×14=5.6×0.45+5.6×0.1×4.1+5.6×0.01×14=5.6×（0.45+0.41+0.14）=5.6×1=5.6

Answer 5

5.6×0.45+0.56×4.1+0.056×14
=0.56*4.5+0.56*4.1+0.56*1.4
=0.56*(4.5+4.1+1.4)
=0.56*10
=5.6
