$$( \frac{ 9 }{ 5 } - \frac{ 1 }{ 5 } )( \frac{ 1 }{ 2 } + \frac{ 1 }{ 2 } )$$
$\frac{8}{5}=1.6$
$$\frac{9-1}{5}\left(\frac{1}{2}+\frac{1}{2}\right)$$
$$\frac{8}{5}\left(\frac{1}{2}+\frac{1}{2}\right)$$
$$\frac{8}{5}\times \frac{1+1}{2}$$
$$\frac{8}{5}\times \frac{2}{2}$$
$$\frac{8}{5}\times 1$$
$$\frac{8}{5}$$
