我刚学了求近似数的值,可还是不太明白。你们谁能教我做这几道题呢?求下面各数的近似数:①6.009;4.384(精确到十分位)②2.8949;9.996(保留两位小数)精确到十分位也就是保留一位小数,只要看小数点后第2位,进行“四舍五入”就行了 I just learned the approximate value, but still do not quite understand. You who can teach me how to do these few questions? Seek the following approximate numbers: ① 6.009; 4.384 (accurate to ten) ② 2.8949; 9.996 (to retain two decimals) accurate to the tenth bit is reserved Decimal place, just look at the second after the decimal point, “rounding” on the line
