$$2.5 : 12.5 ( b ) \frac { 5 } { 8 } : \frac { 7 } { 16 }$$
$\frac{2b}{7}$
$$\frac{\frac{25}{125}b\times \frac{5}{8}}{\frac{7}{16}}$$
$$\frac{\frac{1}{5}b\times \frac{5}{8}}{\frac{7}{16}}$$
$$\frac{\frac{1\times 5}{5\times 8}b}{\frac{7}{16}}$$
$$\frac{\frac{1}{8}b}{\frac{7}{16}}$$
$$\frac{\frac{1}{8}b\times 16}{7}$$
$$\frac{\frac{16}{8}b}{7}$$
$$\frac{2b}{7}$$
