Answer 1

简便计算方法如下

1、提取原式: 5.68×5.9-56.8×0.49

2、计算过程:

=5.68×5.9-5.68×4.9

=5.68×(5.9-4.9)

=5.68×1

=5.68

3、计算结果: 5.68

4、谢谢，期待您的采纳！

Answer 2

5.68×5.9-56.8×0.49
=5.68×5.9-5.68×10×0.49
=5.68×(5.9-0.49×10)
=5.68×(5.9-4.9)
=5.68×1
=5.68

Answer 3

5.68*5.9-56.8*0.49简便计算如下：
5.68*5.9-56.8*0.49
=5.68*5.9-5.68*10*0.49
=5.68*5.9-5.68*（10*0.49）
=5.68*5.9-5.68*4.9
=5.68*（5.9-4.9）
=5.68*1
=5.68

Answer 4

因为5.68×5.9=56.8×0.59，所以原式等于56.8×0.59-56.8×0.49，运用乘法分配律逆运算就是有56.8×（0.59-0.49）=5.68

Answer 5

5.68×5.9－56.8×0.49
=5.68×5.9－5.68×4.9
=5.68×(5.9－4.9)
=5.68×1
=5.68
