$$\frac { 9 } { 5 } + \frac { 19 } { 5 } + ( \frac { - 9 } { 25 } ) + ( \frac { - 4 } { 3 } ) + 1$$
$\frac{368}{75}\approx 4.906666667$
$$\frac{9+19}{5}+\frac{-9}{25}+\frac{-4}{3}+1$$
$$\frac{28}{5}+\frac{-9}{25}+\frac{-4}{3}+1$$
$$\frac{28}{5}-\frac{9}{25}+\frac{-4}{3}+1$$
$$\frac{140}{25}-\frac{9}{25}+\frac{-4}{3}+1$$
$$\frac{140-9}{25}+\frac{-4}{3}+1$$
$$\frac{131}{25}+\frac{-4}{3}+1$$
$$\frac{131}{25}-\frac{4}{3}+1$$
$$\frac{393}{75}-\frac{100}{75}+1$$
$$\frac{393-100}{75}+1$$
$$\frac{293}{75}+1$$
$$\frac{293}{75}+\frac{75}{75}$$
$$\frac{293+75}{75}$$
$$\frac{368}{75}$$
