A digital storage device has a capacity of \(400\ GB\), but an initial report shows that stored files occupy \(125\%\) of this capacity. Express \(125\%\) as both a simplified fraction and a decimal, calculate the total reported amount of data in \(GB\), and calculate how many \(GB\) above the stated capacity this represents.
\(125\%\) as simplified fraction form
\(125\%\) as decimal form
The data above the standard capacity of the digital device is \(GB\).
(Note: If the answer is a whole number, enter it as it is; if it is a decimal value, round off to \(2\) decimal places).
