$$9/48 \times 9/16+9/48 \times -3/9$$
$\frac{11}{256}=0.04296875$
$$\frac{\frac{3}{16}\times 9}{16}+\frac{\frac{9}{48}\left(-3\right)}{9}$$
$$\frac{\frac{3\times 9}{16}}{16}+\frac{\frac{9}{48}\left(-3\right)}{9}$$
$$\frac{\frac{27}{16}}{16}+\frac{\frac{9}{48}\left(-3\right)}{9}$$
$$\frac{27}{16\times 16}+\frac{\frac{9}{48}\left(-3\right)}{9}$$
$$\frac{27}{256}+\frac{\frac{9}{48}\left(-3\right)}{9}$$
$$\frac{27}{256}+\frac{\frac{3}{16}\left(-3\right)}{9}$$
$$\frac{27}{256}+\frac{\frac{3\left(-3\right)}{16}}{9}$$
$$\frac{27}{256}+\frac{\frac{-9}{16}}{9}$$
$$\frac{27}{256}+\frac{-\frac{9}{16}}{9}$$
$$\frac{27}{256}+\frac{-9}{16\times 9}$$
$$\frac{27}{256}+\frac{-9}{144}$$
$$\frac{27}{256}-\frac{1}{16}$$
$$\frac{27}{256}-\frac{16}{256}$$
$$\frac{27-16}{256}$$
$$\frac{11}{256}$$
