小学五年级小数脱式简便计算题带答案

五年级简便脱式计算袭御及答案有如下:

1、24.6-3.98+5.4-6.02

解析:此题利用加法交换结合律州告,凑整再计算。步骤如下:

24.6-3.98+5.4-6.02

=(24.6+5.4)-(3.98+6.02)

=30-10

=20

2、27×17/26

解析:此题先用加法分配律,把27转换成(26+1),再利用乘法结合律,使得运算简便。

27×17/26

=(26+1)×17/26

=26×17/26+1×17/26

=17+17/26

=17又17/26

3、528-99

解析:利用凑整法和减法结合律计算,先利用凑整法把99变换为(100-1),再运用a-b-c=a-(b+c)来简便计算,步骤如下:

528-99

=528-(100-1)拍迹岩

=528-100+1

=428+1

=429

4、1.2×2.5+0.8×2.5

解析:运用提取公因数的方法,公式:ac+ab=a(b+c),提取公因数2.5,1.2和0.8相加正好凑整数,使得运算简便。

1.2×2.5+0.8×2.5

=(1.2+0.8)×2.5

=2×2.5
