Inputting mixed numbers on HP50g

[bootlegend]

Hello,

I just moved to the HP50g from the HP35s. I was wearing out buttons on the 35s at least yearly, so I hope the 50g holds up a little better.

One feature I really liked on the 35s was that I could input mixed numbers by hitting the decimal key between the whole number and between the numerator and denominator. For example, 3 1/4 would be 3,decimal,1,decimal,4,enter and 3.25 would be input. Very handy when adding lists with fractional numbers. So far I haven't been able to figure out if this is possible on the 50g. Definitely isn't set up to do so right out of the box. I've done some searching but haven't found anyone discussing this issue.

Can anyone tell me if what I describe is possible on the 50g?

Thanks.
