Question

24.6×14.3-24.6-24.6×3.6用简便算法计算？

Answer 1

这个可以提取公因式就可以简便计算。
24.6×14.3-24.6-24.6×3.6
=24.6×(14.3-1-3.6)
=24.6×8.7
=214.02

Answer 2

24.6＊14.3-24.6-24.6＊3.6
＝24.6＊（14.3-1-3.6）
＝24.6＊9.7
＝24.6＊（10-0.3）
＝246-7.38
＝246-（10-2.62）
＝246-10+2.62
＝236+2.62
＝238.62

Answer 3

24.6×14-24.6-24.6×3.6
=24.6×14.3-24.6×1-24.6×3.6
=24.6×（14.3-1-3.6）
=24.6×9.7
=24.6×（10-0.3）
=24.6×10-24.6×0.3
=246-7.38
=238.62

Answer 4

=24.6×（14.3-1-3.6）=24.6×9.7=（25-0.4）×（10-0.3）=250-7.5-4+0.12=238.62

Answer 5

24.6×14.3-24.6-24.6×3.6的简算：
24.6×14.3-24.6-24.6×3.6
=24.6×(14.3-1-3.6)
=24.6×9.7
=238.62
