【蓝猫出题】一个三位小数的近似数是0.5,这个小数最大是多少?最小是多少?●【淘气出招】●一个三位小数的近似数是0.5,是将这个三位小数精确到了十分位。这样看来,就要分析这0.5是由原三位小数中百分位数的“四舍”取的近似数,还是“五入”取的近似数。
[Blue cat title] a three-digit decimal approximation is 0.5, the largest number of what is the smallest? What is the smallest? ● [naughty move] ● a three decimal approximation is 0.5, is the three decimal precision To the very place. In this case, it is necessary to analyze whether the 0.5 is an approximation taken from the quartiles of the percentiles in the original three decimal places or an approximation taken from the “five in”.
