30.6×0.17+8.3×3.06怎样简便就怎样算？

Answer 1

巧算30.6×0.17+8.3×3.06
解题思路：四则运算规则（按顺序计算、先算乘除后算加减，有括号先算括号，有乘方先算乘方）即脱式运算（递等式计算）需在该原则前提下进行
解题过程：

30.6×0.17+8.3×3.06

=30.6×(1.7+8.3)

=30.6×10

=30.6

Answer 3

简便计算过程如下
30.6+0.17+8.3×3.06
=30.6×0.17+8.3×0.1×30.6
=30.6×0.17+0.83×30.6
=30.6×（0.17+0.83）
=30.6×1
=30.6
望采纳

Answer 4

30.6×0.17+8.3×3.06

=3.06×1.7+8.3×3.06..............积的小数点与因数的小数点的关系

=3.06×（1.7+8.3）..............乘法的分配律

=3.06×10

=30.6

Answer 5

原式=3.06×(1.7+8.3)
=3.06×10
=30.6
