Two friends, Alejandro and Mia, agreed to split the check at a restaurant. Alejandro ordered $/$12$ worth of food and Mia ordered $/$18$ worth. At the end of the meal, Alejandro put his $/$12$ contribution on the table, plus a $20/%$ tip on his bill and Mia put her $/$18$ contribution on the table, plus a $15/%$ tip on her bill.

The total tip left by Alejandro and Mia is equal to $r/%$ of the total check for their table, where the "total check" amount does not include the tip. What is $r$?
