Mixed Fractions on the HP Prime
My son is learning how to do arithmetic using mixed fractions. The other night I needed to check his homework. My assumption was that on the HP Prime it would be easy and fast to check a series of mixed fraction addition and subtraction problems. But, I found I could only do this by switching between CAS and HOME, a bit cumbersome. There must be an easier way?

For example: 5 3/4 + 11 7/9 = 17 19/36

My Procedure:
[CAS] 5 + 3/4 + 11 + 7/9 <Enter>
631/36 (a b/c)
(Menu) 2Get from CAS
17.52777777778 <Enter>
(a b/c)
(a b/c)
17+19/36 Finally!
