Answer 1

这是小学五年级数学简便运算内容，一般都是用乘法交换律结合律和分配率率解决，具体解答过程如下:
4.44×9.8×2.5
=4×1.11×9.8×2.5
=(4×2.5)×1.11×9.8
=10×1.11×9.8
=11.1×9.8
=108.78
希望我的回答对您有帮助！！！

Answer 2

4.44×2.5×9.8 简便算法是:

Answer 3

原式=4×1.11×9.8×2.5
=1.11×9.8×10
=1.11×98
=1.11×(100-2)
=111-2.22
=108.78
请采纳，谢谢。

Answer 4

将9.8分成10-0.2.4.44分成4×1.11.原式＝1.11×4×2.5×（10-0.2）＝1.11×10（10-0.2）＝11.1（10-0.2）＝111-2.22＝108.78

Answer 5

4.44×9.8×2.5
=4×1.11×9.8×2.5
=4×2.5×1.11×9.8
=10×1.11×9.8
=1.11×98
=1.11×（100-2）
=111-2.22
=108.78
