Yep pulled a noob. I totally forgot how to enter complex dimensions in the dynamic prompt. In my defense there is a lot in my day to day that actually doesn't require scale or precision on that level.

For the noobs who land here for the same problem, just add a dash.
7 and 3/4 inches is put in like the following:
and with this I go crawl in a corner in total noob self pitty...
