Question

5.6×0.34+0.56×4.37的简便方式？

Answer 1

5.6×0.34+0.56×4.37
=5.6×0.34+(0.56×10)×(4.37÷10)
=5.6×0.34+5.6×0.437
=5.6×(0.34+0.437)
=5.6×0.777
=4.3512

Answer 2

原式=0.56*3.4+0.56*4.37
=0.56*（3.4+4.37）
=0.56*7.77
=8*0.7*7*1.11
=8.88*0.49
=8.88*0.5-8.88*0.01
=4.44-0.0888
=4.3512

Answer 3

5.6*0.34+5.6*0.437=5.6*（0.24+0.437）=5.6*0.677=3.7912

Answer 4

本题的简便运算如下：
=5.6*0.34+5.6*0.437
=5.6*（0.34+0.437）
=5.6*0.777
=4.3512

Answer 5

5.6×0.34+0.56×4.37这个题怎么算也不简单，没有简便运算，用老办法，先乘除，后加减。
