1. (8 points) Among all the simplest fractions with denominators less than 10, the fraction closest to 20.14 is ( )
A. $\frac{101}{5}$
B. $\frac{141}{7}$
C. $\frac{181}{9}$
D. $\frac{161}{8}$
【Solution】Solution: $A . \frac{101}{5}=20.2,20.2-20.14=0.06$
$$
\begin{array}{l}
\text { B. } \frac{141}{7} \approx 20.14,20.14-20.14=0 \\
\text { C. } \frac{181}{9} \approx 20.11,20.14-20.11=0.03 \\
\text { D. } \frac{161}{8}=20.125,20.14-20.125=0.015
\end{array}
$$

Therefore, the correct choice is: $B$.
