Answer 1

Fraction Form:
`(2187)/(4000000)`

Decimal Form:
`0.000547`

Explanation:

`=(5)/(256) * (3)/(5)^1^2 / (3)/(5)^5`

`(3)/(5)^1^2/(3)/(5)^5=(2187)/(78125)`

`=(5)/(256)*(2187)/(78125)`

`\mathrm{Apply\:the\:fraction\:rule}:\quad (a)/(b)\cdot (c)/(d)=(a\:\cdot \:c)/(b\:\cdot \:d)`

`(5*2187)/(256*78125)`

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

`=(5*2187)/(256*5*15625)`

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

`=(2187)/(256*15625)`

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

`(2187)/(4000000)`
