0.44x0.25 4简便计算

0.44*0.25=0.11*4*0.25=0.11*1=0.11

4.08*0.25 =(4+0.08)*0.25 =0.25*4+0.25*0.08 =1+0.02 =1.02 扩展资料:1、乘法简便计算规律:乘法交换律:a*b=b*a,乘法结合律:a*b*c=(a*b)*c=a*(b*c),乘法分配律:(a+b)*c=a*c+b*c;(a-b)*c=a*c-b*c.2、加法简便计算规律:加法交换律; 加法结合律.3、减法简便计算规律:减法的基本性质.4、除法简便计算规律:除法的基本性质;商不变的性质.5、简算特殊公式:25*2=50,25*3=75,25*4=100,25*8=200.

运用乘法分配律: 0.44*0.25=(0.4+0.04)*0.25= 0.4*0.25+0.04*0.25= 0.1 + 0.01= 0.11

4.44*0.25=(4+0.4+0.04)*0.25=4*0.25+0.4*0.25+0.04*0.25=1+0.1+0.01=1.114.44*0.25=4.44*1/4=1.11

4.44*0.25简便计算4.44*0.25=1.11*4*0.25=1.11*1=1.11

原式=(1.11x4)x0.25=1.11x(4x0.25)=1.11x1=1.11 或者=4x0.25+0.4x0.25+0.04x0.25=1+0.1+0.01=1.11

如图所示

0.44÷0.25-0.4*4=0.44*4-0.4*4=(0.44-0.4)*4=0.04*4=0.16

0.25*4÷0.25*4=0.25÷0.25*4*4=1*4*4=16

4.44*0.25=1.11*(4*0.25)=1.11
