四年级简便计算题100道带答案1、1.2×2.5+0.8×2.5
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
2、46×44/45
此题先利用加法分配律把46转换成(45+1),再利用乘法结合律:(a×b)×c=a×(b×c)使得运算简便。
46×44/45
=(45+1)×44/45
=45×44/45+44/45
=44+44/45
=44又44/45
3、1.6×7.5×1.25
此题利用乘法分配律把1.6,转化成2×0.8,再利用乘法结合律:(a×b)×c=a×(b×c)凑整,进行简便计算。
1.6×7.5×1.25
=2×0.8×7.5×1.25
=(2×7.5)×(0.8×1.25)
=15×1
4、250+616÷28×15
此题先利用分配法将616转换成560+56,再提取公约数28,然后按照乘法结合律,使得运算简便。
250+616÷28×15
=250+(560+56)÷28×15
=250+(20+2)×15
=250+300+30
5、35x62+70x19
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
