Is it right 13rd? or 13th?
Interesting question, Revere.
3rd - third
13th - thirteenth (it's not formed in the same way as the others: cardinal numeral + third)
23rd - twenty-third
33rd - thirty-third
13th is right. If you spell it out, it will be thirteenth.
If it is a fraction 1/3, then you say it out as one third.
Separate names with a comma.
