Answer:
2/6 quart or 1/3 quart
Explanation:
Each of these fractions already have a common denominator, so we can add the numerators to get the amount of ice cream eaten in total. 1/6+3/6=4/6. Now, we have the option to simplify or not, most teachers want you to simplify. 4/6 simplifies to 2/3 (every 2/6 is 1/3). That is how much has been eaten. To find out how much is left, take the original value and subtract the amount eaten. 1 quart (or 6/6 or 3/3) - 2/3 (or 4/6) = 2/6 or 1/3.
