五年级上册简便计算是有如下:
1、24.6-3.98/1+5.4-6.02
解析:此题利用加法交换结合律,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),再利用乘法结合旅祥律,使得运算简便。步骤如下:
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:利迟轿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)
=528-100+1
=428+1
=429
4、1.2×2.5+0.8×2.5
