$$A=\frac{1}{5}+\frac{7}{16}\times\frac{8}{4}$$
$A = \frac{43}{40} = 1\frac{3}{40} = 1.075$
$$A=\frac{1}{5}+\frac{7}{16}\times 2$$
$$A=\frac{1}{5}+\frac{7\times 2}{16}$$
$$A=\frac{1}{5}+\frac{14}{16}$$
$$A=\frac{1}{5}+\frac{7}{8}$$
$$A=\frac{8}{40}+\frac{35}{40}$$
$$A=\frac{8+35}{40}$$
$$A=\frac{43}{40}$$
