Hi serge
the printing should be normal because like that you are ready to type 1/3 + 2/3 and get 1.
No, not at all: 1/3 + 2/3 "(7/9)" These are all just binary messages evaluated left to right, like this: ((1/3) + 2)/3 "(7/9)" That is why you need the parenthesis in certain contexts. Now adding two of them is definitively wrong. (1/3) + (2/3) "1" (The first parenthesis are not needed, btw).
Now I do not get why you get ((1/2)) thanks for reporting it.

When I print a fraction like 1/2 in the Playground I obtain (1/2) and when I inspect I obtain ((1/2)). Why do we need all these parentheses ?
I didn't try with a current Pharo 6.0 image, because my bandwidth is quite limited right now (Vietnam).
