五乘7.26除以1.2用简便计算怎么算

五乘7.26除以1.2可以写成:5×7.26÷1.2。简便计算过程如下: 5×7.26÷1.2 =5×7.26÷(0.6×2) =5×7.26÷0.6÷2 =5×(7.26÷0.6)÷2 =5×12.1÷2 =60.5÷2 =30.25 扩展资料: 乘法的运算定律: 1)乘法交换律:a*b=b*a; 2)乘法结合律:a*b*c=(a*b)*c=a*(b*...

脱式计算,能简算要简算 13/6÷39/14×24/7÷26/5 =13/6×14/39×24/7×5/26 =7/9×24/7×5/26 =3/8×5/26 =15/208

哪里的

运用乘法分配律把3.26提出来,等于3.26×(5.7-0.7)然后先算括号里面的,等于3.26×5最后答案是16.3

3.26X5.7-32.6X0.07 =3.26X(5.7-0.7) =3.26X5 =16.3

4.5*3.26+9.7*6.74+3.26*5.2=3.26*(4.5+5.2)+9.7*6.74=3.26*9.7+9.7*6.74=9.7*(3.26+6.74)=97

解:依题意得算式, 7分之6+24分之13×26分之15+16分之11 =7分之6+16分之5+16分之11 =7分之6+(16分之5+16分之11) =7分之6+1 =1又7分之6

7又5分之3乘3.6+0.36除以50分之1-36乘百分之26 =7.6*3.6+0.36*50-36*0.26 =36(0.76+5-0.26) =36*5.5 =198

四点二除以零点7+6乘25分之一的和乘二十六分之五 =(4.2÷0.7+6×1/25)×5/26 =(6+6×1/25)×5/26 =6×(1+1/25)×5/26 =6×26/25×5/26 =6/5 =1又1/5。

简便计算 74×54+26×54 =(74+26)×54 =100×54 =5400
