Answer 1

The correct option is D

$\frac{1}{5}$

$9\frac{1}{2}\times \frac{2}{7}\times \frac{7}{19}\times \frac{1}{5}$

= $\frac{19}{2}\times \frac{2}{7}\times \frac{7}{19}\times \frac{1}{5}$

= $(\frac{19}{2}\times \frac{2}{7}\times \frac{7}{19})\times \frac{1}{5}$

= $1\times \frac{1}{5}$

= $\frac{1}{5}$
