if d=3.0641 and d(上面有一横) is the number obtained by rounding d to the nearest hundredeth, then d-d(上面有一横)= (A) 0.0001 (B) 0.0041 (C) 0.0059 (D) 0.0141 (E) 0.0410 问题: 1. d上面有一横是什么意思啊? 2.这道题翻译成中文是什么意思? 3.怎么做?
是不是B啊?the number obtained by rounding d to the nearest hundredeth把d取2位小数的近似值。
只是一个符号,让你求3.0641与其四舍五入小数点后百位的差,3.0641-3.06=0.0041
