In a 12-egg carton, 1/6 of the carton represents 3 eggs.
In a 12-egg carton, 1/6 represents the fraction of the carton filled by 3 eggs. To determine this, divide the total number of eggs (12) by the denominator of the fraction (6). This gives us 2, which represents the value of each unit in the fraction. Therefore, multiplying 2 by the numerator of the fraction (1) yields 2 eggs. Since 1/6 of the carton is equal to 2 eggs, we can conclude that each unit in the fraction corresponds to 3 eggs.
