3.26×5.7%3.26×0.7怎样简便算

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

3.26x5.7-3.26x0.7 =3.26x(5.7-0.7) =3.26x5 =16.3

3.26x5.7-3.26x0.7 =3.26x(5.7-0.7) =3.26x5 =16.3 考察乘法分配律的应用 祝天天向上。

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

简便运算 5.7×26+26×3.2+26×1.1 =(5.7+3.2+1.1)×26 =10×26 =260

1.3x(5十0.7)一3.26x0.7 =(1.3x5十0.7X1.3)一3.26x0.7 =(6.5十0.7x1.3)一3.26x0.7 =6.5十(3.26一1.3)x0.7 =6.5十1.96X0.7 =6.5十1.372 =7.872

3/26×5/7×39 =3/26×39×5/7 =9/2×5/7 =45/14

先算26.7×2.5再+43.3 在数学中,当一级运算(加减)和二级运算(乘除)同时出现在一个式子中时,它们的运算顺序是先乘除,后加减,如果有括号就先算括号内后算括号外,同一级运算顺序是从左到右,这样的运算叫四则运算。 四则是指加法、减法、乘法、...

43点3+26点7×2点五的简便方法 43点3+26点7×2点五 =43.3+66.75 =110.05 直接计算

1/4×39+3/4×26.5+7/4×3/14 =1/4×3×13+3/4×26.5+3/4×1/2 =3/4×(13+26.5+0.5) =3/4×40 =30
