五年级上数学简便计算规律及练习

小学数学五年级上册简便计算专项练习 简便计算例题: 乘法结合律: 规律:在连乘算式中如果发现有因数25就找因数4,有因数125就找因数8,因为25×4=100,125×8=1000。 0.25×4.78×4 1.25×24 5.75×3.27÷5.75 =0.25×4×478 =1.25×8×3 (24=8×3)=5.75÷5.75×3.27 =1×4.78 =10×3 =1×3.27 =4.78 =30 =3.27 乘法分配律: 规律1:在乘法算式中如果有因数接近整百数,就先按整百数先乘再,然后再加上或减去相应的数乘以另一个因数的积。如: 0.65×201(201=(200+1)) 3.8×99 (99=100-1) =0.65×(200+1)=3.8×(100-1) =0.65×200+0.65×1 =3.8×100-3.8×1 =130+0.65 =380-3.8 =130.65 =376.2 规律2:在几个乘法算式相加、减的题中,如果发现几个乘法算式中有共同的因数,可以先把这个共同因数乘以另外几个因数相加、减的得数。如: 3.64×0.43+0.43×5.36+0.43 43×3.5-6×3.5 =0.43×(3.64+5.36+1)(0.43=0.43×1)=3.5×(12.57+3.43-6) =0.43×10 =3.5×10 =4.3 =35 除法性质应用: 42.35÷2.5÷4 5.6÷3.5 =42.35÷(2.5×4)=5.6÷(7×0.5) =42.35÷10 =5.6÷7÷0.5 =4.325 =0.8 ÷0.5=1.6 请用简便方法计算下列各题 0.25×0.28 0.125×3.2×2.5 35×40.2 0.25×4÷0.25×4 3.5×9.9 3.5×99+3.5 3.5×101-3.5 3.5×9.9+3.5×0.1 3.5×2.7+35×0.73 3.5×2.7-3.5×0.7 (32+5.6)÷0.8 3.5÷0.6-0.5÷0.6 4.9÷3.5 7÷0.25÷4 7÷0.125 ÷8
