Estimate to determine which of the following is closest to

$\frac{401}{.205}.$

$.2$

$2$

$20$

$200$

$2000$

知识点：估算

把分子和分母分别取成便于计算的近似数，得到 $\frac{401}{.205} \approx \frac{400}{.2}$ 。

由于 $\frac{400}{.2} = 2000$ ，原数最接近 $2000$ 。

所以正确答案是 E。

Round the numerator and denominator: $\frac{401}{.205} \approx \frac{400}{.2}.$

Since $\frac{400}{.2} = 2000,$ the value is closest to $2000.$

Thus, the correct answer is E .
