#r > 0#

Explanation:

#- 1/3 < r - 1/3#
P.S. We always want to make sure that the variable we are trying to solve is in front. It makes it more easier to solve. So we gonna do that by "Flipping the equation".
#r+ (- 1)/3 > (-1)/3#
Now all we have to do is to add #color(red)(1/3)# to both sides
#r + (-1)/3+color(red)(1/3) > (-1)/3 + color(red)(1/3)#
When we simplify this problem we will get #0#
Therefor,
#r >0#
