Answer 2

${(\frac{3}{2})}^{3}\div {(\frac{3}{4})}^{6} \times {(\frac{2}{4})}^{2}$

$= {\frac{27}{8}}\div {(\frac{3}{4})}^{6} \times {(\frac{2}{4})}^{2}$

$= {\frac{27}{8}}\div {\frac{729}{4096}}\times {(\frac{2}{4})}^{2}$

$= {\frac{512}{27}}\times {(\frac{2}{4})}^{2}$

$= {\frac{512}{27}}\times {(\frac{1}{2})}^{2}$

$= {\frac{512}{27}}\times {(\frac{1}{4})}$

$= \frac{128}{27}$
