David is pouring an entire gallon of milk into 12 glasses. what part of a gallon will be in each glass

This question calls for a fraction.  In a fraction, the numerator (top number) is the number of parts, while the denominator (bottom number) is the total number of parts.  One part is one glass of milk, and there are 12 parts total.  So, we get the answer 1/12.

1/12

1/12. There are 12 parts so a unit fraction would be 1/12. Hope this helps!
