Question

24.6×4.6+24+6×0.44+24.6简便计算

Answer 1

24.6×4.6+24+6×0.44+24.6
=(24.6×4.6+24.6)+6+2.64
【括号内提取24.6】
=24.6×(4.6+1)+8.64
=24.6×5.6+8.64
=24.6×7×0.8+8.64
=172.2×0.8+8.64
=137.76+8.64
=146.4

Answer 2

计算过程如下：
24.6×4.6+246×0.44+24.6
=24.6×4.6+24.6×4.4+24.6×1
=24.6×（4.6+4.4+1）
=24.6*10
=246.
用到的知识是乘法的结合律。

Answer 3

24.6x4.6+24+6x0.44+24.6
=6x(4.1x4.6+4+0.44+4.1)
=6x(4.1x5.6+4+0.44)
=6x[(4+0.1)x5.6+4+0.44)
=6x(22.4+0.56+0.44+4)
=6x27.4=6x(25+2.4)
=150+14.4
=164.4

Answer 4

题目大概是多了个加号
24.6×4.6+246×0.44+24.6
=24.6×(4.6+1)+24.6×4.4
=24.6×(5.6+4.4)
=246
