400道四年级上册的脱式计算并有答案。
1、92+92×99 解析:此题可以利用乘法结合律,将1与99结合,组成100,再与92相乘,使得运算简便。 92+92×99 =92×1+92×99 =92×(99+1) =92×100 =9200 2、6.07+0.4-0.08 解析:此题的小数之前没有规律不方便计算,可先利用分配律把0.08转换成0.07+0.01,再利用加法结合律进行简便计算。 6.07+0.4-0.08 =6.07+0.4-(0.07+0.01) =6.07+0.4-0.07-0.01 =6.07-0.07+0.4-0.01 =6+0.4-0.01 =6.4-0.01 =6.39 3、8.2-9.6x0.5 解析:此题先计算乘法,再计算减法,脱式算法如下: 8.2-9.6x0.5 =8.2-4.8 =3.4 4、35x62+70x19 解析:此题先利用乘法分配律把70变换成35成2,再利用乘法分配律的逆运用提取公约数35,最后利用乘法结合律来简便计算。 35x62+70x19 =35x62+35x2x19 =35x62+35x38 =35×(62+38) =100×35 =3500 5、24.6-3.98+5.4-6.02 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

❽ 四年级脱式计算题400道有过程和答案
1、24.6-3.98+5.4-6.02
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
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、50×49×2
此题运用乘法交换律:a×b=b×a,交换3个数的位置,先计算50×2,再跟49相乘,使得运算简便。
50×49×2
=50×2×49
=100×49
=4900
4、4.27÷26.8x3.59÷42.7x2.86÷35.9
此题先使用乘除法的交换律,交换各个数的位置,再分别运算,使得运算简便。
4.27÷26.8x3.59÷42.7x2.86÷35.9
=4.27÷42.7×2.68÷26.8×3.59÷35.9
=0.1×0.1×0.1
=0.001
5、3.5×4/5+5.5×80%+0.8
此题先把4/5和80%换算成0.8,0.8写作1×0.8,再利用乘法分配律做简便计算,方法如下:
3.5×4/5+5.5×80%+0.8
=3.5×0.8+5.5×0.8+1×0.8
=(3.5+5.5+1)×0.8
=10×0.8
=8
