To find the sum of 2/3 and 1/4, first, we need to find a common denominator. The denominators here are 3 and 4. The least common multiple of 3 and 4 is 12, which will be our common denominator.

Next, we convert each fraction to have a denominator of 12. For 2/3, we multiply both the numerator and the denominator by 4:

(2 * 4) / (3 * 4) = 8/12.

For 1/4, we multiply both the numerator and the denominator by 3:

(1 * 3) / (4 * 3) = 3/12.

Now, we can add these two fractions:

8/12 + 3/12 = (8 + 3) / 12 = 11/12.

Therefore, the sum of 2/3 and 1/4 is 11/12, which is why this choice is the correct answer. It accurately represents the combined total expressed in the simplest form with a common denominator.
