Baker had 36 eggs Baker made 3 batches of cookies Each batch required 9 eggs 9 eggs x 3 batches =27 36-27=9 9eggs out of the dozen =3/4 dozen eggs remaining
So one way you can do it is to multiply 12 by 3/4 which equals 9. Then you can multiply 9 by three since one dozen is 12. So once you multiply 9 by three you get your answer.
