Solve as below
\(\displaystyle{2}{\left({\frac{{{17}}}{{{5}}}}\right)}={\frac{{{2}\cdot{17}}}{{{5}}}}\)

\(\displaystyle={\frac{{{34}}}{{{5}}}}\)

\(\displaystyle={6.8}\) Therefore, the solution for \(\displaystyle{2}{\left(={\frac{{{17}}}{{{5}}}}\right)}={\frac{{{34}}}{{{5}}}}\) (in fraction) or 6.8(in decimals).

\(\displaystyle={\frac{{{34}}}{{{5}}}}\)

\(\displaystyle={6.8}\) Therefore, the solution for \(\displaystyle{2}{\left(={\frac{{{17}}}{{{5}}}}\right)}={\frac{{{34}}}{{{5}}}}\) (in fraction) or 6.8(in decimals).
