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 =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 =15 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 =580 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
