2 1/2% can be expressed as a fraction before we can use it to solve:

$\begin{gathered} 2(1)/(2)=(5)/(2) \\ (5)/(2)\%=(5)/(2)*(1)/(100)=(5)/(200)=(1)/(40) \end{gathered}$

Let the unknown number be x.

2 1/2% of x can be written to be:

$2(1)/(2)\%* x=(1)/(40)x$

If the result is 8, then we have:

Therefore, the answer will be:

$\begin{gathered} x=40*8 \\ x=320 \end{gathered}$

The answer is 320.
