13:9 without simplifying. Also you might get extra credit if you say this :) ( For every 13 chickens there are are 9 roosters!
TRY TO SEE IF YOU CAN SIMPLIFY:
Easy way to simplify find the GCF ( greatest common factor ) of 13 and 9. Replace the 13 and the 9.
After you replaced them.
YOUR DONE.
- hope this helped
