What is the positive difference between $$\frac{5}{16}$$​ and its reciprocal?

Correct option is C

Given:

Number $$= \frac{5}{16}$$​​

Solution:

Reciprocal of $$\frac{5}{16} = \frac{16}{5}$$​

​$$\left| \frac{16}{5} - \frac{5}{16} \right| = \left| \frac{(16 \times 16 - 5 \times 5)}{80} \right| = \left| \frac{256 - 25}{80} \right| = \frac{231}{80} = 2\frac{71}{80}$$​​
