2/3 + 1/12

To add these fractions, we first need to find a common denominator. The smallest number that both 3 and 12 divide into evenly is 12.

Now, we'll convert the fractions to have a denominator of 12:

2/3 = (2 * 4) / (3 * 4) = 8/12
1/12 = 1/12 (already in the desired form)

Now, we can add the fractions together:

8/12 + 1/12 = (8 + 1) / 12 = 9/12

The final answer is 9/12, which can also be simplified to 3/4 by dividing the numerator and denominator by 3.
