Step-by-step explanation:

$\frac{81 \times 8}{32 \times 243} \\ = \frac{3 {}^{4} \times 2 {}^{3} }{2 {}^{5} \times 3 {}^{5} } \\ = \frac{1}{2 {}^{5 - 3} \times 3 {}^{5 - 4} } \\ \frac{1}{2 {}^{2} \times 3 {}^{1} } \\ \frac{1}{12}$

$\frac{3 {}^{7} \times 2 {}^{5} }{3 {}^{6} \times 2 {}^{8} } \\ = \frac{3 {}^{7 - 6} }{2 {}^{8 - 5} } \\ = \frac{3 {}^{1} }{2 {}^{3} } \\ = \frac{3}{8}$
