Hi there!
Unfortunately, it looks like what you've posted is already simplified down to its simplest form, and so it cannot go any lower than what it is.
[tex]8 \frac{1}{4} [/tex]
⇒ The decimal form of this answer is [tex]8.25[/tex]
Hope this helps!
Message me if you need anything else! I'd be happy to answer more questions! :D
