(6.6+6.7+6.8)—(5.2+5.3+5.4)的简便计算怎么写？

Question

如题所述

Answer 1

本题是小学六年级数学简便运算内容，本题不同于其他题目，一定要注意观察，然后得出解决办法，具体解答过程如下:
(6.6+6.7+6.8)-(5.2+5.3+5.4)
=3×6.7-3×5.3
=3×(6.7-5.3)
=3×1.4
=4.2
希望我的解答对你有所帮助！

Answer 2

(6.6+6.7+6.8)-(5.2+5.3+5.4)
=(6.6-5.2)+(6.7-5.3)+(6.8-5.4)
=1.4+1.4+1.4
=2.8+1.4
=4.2本回答被网友采纳

Answer 3

6.6-5.2+6.7-5.3+6.8-5.4
=1.4+1.4+1.4
=1.4x3
=4.2
以上就是简便方法。

Answer 4

(6.6+6.7+6.8)-(5.2+5.3+5.4)
=(6.6-5.2)+(6.7-5.3)+(6.8-5.4)
=1.4+1.4+1.4
=4.2

Answer 5

（6.6+6.7+6.8）-（5.2+5.3+5.4）
=6.7×3-5.3×3
=（6.7-5.3）×3
=1.4×3
=4.2
