Answer:

Fraction Form: $\frac{2187}{4000000}$

Decimal Form: $0.000547$

Step-by-step explanation:

$=\frac{5}{256} * \frac{3}{5}^1^2 / \frac{3}{5}^5$

$\frac{3}{5}^1^2/\frac{3}{5}^5=\frac{2187}{78125}$

$=\frac{5}{256}*\frac{2187}{78125}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}$

$\frac{5*2187}{256*78125}$

$\mathrm{Factor\:the\:number:\:}\:78125=5\cdot \:15625$

$=\frac{5*2187}{256*5*15625}$

$\mathrm{Cancel\:the\:common\:factor:}\:5$

$=\frac{2187}{256*15625}$

$\mathrm{Multiply\:the\:numbers:}\:256\cdot \:15625=4000000$

$\frac{2187}{4000000}$
