5.25✘1.4-2.7✘5.25+5.25✘11.3怎么简便计算？

Answer 1

简算5.25×1.4-2.7×5.25+5.25×11.3
解题思路:不能进行简便运算的按顺序计算,简便运算核心是运用加法和乘法各种定律进行计算,计算出整数部分方便后续计算的过程

解题过程:
5.25×1.4-2.7×5.25+5.25×11.3

=5.25×(1.4-2.7+11.3)

=5.25×10

=52.5

存疑请追问,满意请采纳

Answer 2

5.25x1.4-2.7x5.25+5.25x11.3
=5.25x(1.4-2.7+11.3)
=5.25x(1.4+11.3-2.7)
=5.25x(12.7-2.7)
=5.25x10
=52.5

Answer 3

这个很容易，关键是同类项的合并
=5.25*（1.4-2.7+11.3）
=5.25*10
=52.5
满意望采纳

Answer 4

5.25×1.4－2.7×5.25+5.25×11.3
=5.25×(1.4－2.7+11.3)
=5.25×(1.4+11.3－2.7)
=5.25×10
=52.5

Answer 5

原式=5.25x（1.4-2.7+11.3）
=5.25x（12.7-2.7）
=5.25x10
=52.5
