2.7×3.7+0.37×0.8简便计算,并说明运

解:运用拆分法和提取公因式的简便方法, 原式=27x0.37+0.37x0.8 =0.37x(27+0.8) =0.37x27.8 =10.286

1.37×0.2-0.37×0.2 =(1.37-0.37)×0.2 =1×0.2 =0.2 你好,本题已解答,如果满意 请点右下角“采纳答案”。

2.37×6.36+23.7×0.37用简便计算怎么算 2.37×6.36+23.7×0.37 =2.37*(6.36+3.7) =2.37*(10+0.06) =2.37*10+2.37*0.06 =23.8422

2.7×3.7 0.37×73的简便运算 2.7×3.7+0.37×73 =2.7×3.7+3.7×7.3 =3.7×(2.7+7.3) =3.7×10 =37.

3.7×0.53+0.37×4.4+0.37×0.3 =3.7×0.53+3.7×0.44+3.7×0.03 =3.7×(0.53+0.44+0.03) =3.7×1 =3.7

3.7×9.8+37×0.02 =3.7×9.8+3.7×0.2 =3.7×(9.8+0.2) =3.7×10 =37

2.7x3.7+0.37x73 =2.7×3.7+0.37×(10×7.3) =2.7×3.7+3.7×7.3 =3.7×(2.7+7.3) =3.7×10 =37

(1)2.37×6.3+2.37×3.7=(6.3+3.7)×2.37,=10×2.37,=23.7;(2)2.5×1.25×0.32=2.5×1.25××0.4×0.8,=(2.5×0.4)×(1.25×0.8),=1×1,=1;(3)4.4×25 =(4+0.4)×25,=4×25+0.4×25,=100+10,=110;(4)2.64÷5÷0.2=2.64÷(5×0.2),=2.64...

简便计算 9.8×8.5 =10×8.5-0.2×8.5 =85-1.7 =83.3 4.63×3.8+3.37×6.2 =1.26×3.8+3.37×3.8+3.37×6.2 =4.788+3.37×(3.8+6.2) =4.788+3.37×10 =4.788+33.7 =38.488 0.125×13.7×0.4 =(0.125×0.4)×13.7 =0.05×13.7 =0.665

你好,可以这样算 3.7*10-0.37+0.37=37
