0.347怎么样约等于1/3 保留一位小数约等于:0.3 解析 约等于就是大约多少的意思,是一个估计的数字,按四舍五入算法进行计算。 约等于通常会告知精确到的位数,如精确到十位,按四舍五入算法,假如个位上的数字在4以下就要去掉,假如个位上的数...

解:运用加法交换律、结合律: 7.4+0.34-7.4+0.034 =(7.4-7.4)+(0.34+0.034) =0+0.0374 =0.0374

(-3)×2/3-0.34×2/7 =-2-17/50×2/7 =-2-17/175 =-2又17/175。

6.25×0.56+0.347×3.4+5×0.125 =0.625×5.6+0.625×1+0.347×3.4 =0.625×(5.6+1)+0.347×3.4 =0.625×6.6+(0.625-0.278)×3.4 =0.625×6.6+0.625×3.4-0.278×3.4 =0.625×(6.6+3.4)-0.278×3.4 =6.25-(0.278×3+0.278×0.4) =6.25-(0.834+0.1112) =6.25-0.94...

5.7×0.34+43×3.4 =0.57×10×0.34+43×3.4 =0.57×3.4+43×3.4 =(0.57+43)×3.4 =43.75×3.4 =148.75
