1.76除以412点24目录
简便计算
过程如下，望采纳
41.2x8.1 11x1.25 53.7ⅹ1.9
=41.2x8.1 1.1x12.5 (41.2 12.5)x1.9
=41.2×(8.1 1.9) 12.2×(1.1 1.9)
=41.2×10 12.5
×3
=412 37.5
=449.5
41.2x8.1 11x1.25 53.7x1.9
=41.2x8.1 41.2×1.9 12.5×1.9 1.1x12.5
=41.2×（8.1 1.9） 12.5×（1.9 1.1）
=41.2×10 12.5×3
=412 37.5
=449.5
解答分析：
此题的重点是把53.7x1.9拆分成41.2×1.9 12.5×1.9
然后按乘法分配律分组进行计算。
乘法分配律公式a×b a×c=a×（b c）
41.2×8.1 4.12×23-412×0.04
=41.2×8.1 41.2×2.3-41.2×0.4
=41.2×（8.1 2.3-0.4）
=41.2×10
=412
