Keeping fractions together

[donandjudy1]

Hello:

How do I keep fractions and mixed numbers written in standard slash and
dash, e.g. 1/16" or 2-3/8", together when they wind up at the end of a line?

I'm aware of fraction fonts, but am hoping there's some way to add them to
the personal dictionary or otherwise get them on a spelling list without
changing the style in which they are typed.

Any help would be appreciated.
