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

=3.26×(5.7-0.7) =3.26×5 =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

3.29×15.7-3.26×5.7 =3.29×(10+5.7)-3.26×5.7 =3.29×10+3.29×5.7-3.26×5.7 =32.9+5.7×(3.29-3.26) =32.9+5.7×0.03 =32.9+0.171 =33.071

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

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、...

=7.26-5.26+3.7 =2+3.7 =5.7

32.6xo.57一3.26x0.7 =3.26x5.7-3.26x0.7(32.6缩小10变成3.26, 0.57扩大10 变成5.7 ) =3.26x(5.7-0.7) =3.26x5 =16.3
