– So how was the first day in kindergarden?
– Boring! said Pat.
– Booooring! joined Chris.
– How come? asked the concerned father.
– 12/17 of the other kids were girls! sighed Pat.
– Really! I found that 5/7 of the other kids were girls!
How many girls and boys were in the kindergarden, and what are the genders of Pat and Chris?
