2/3 + 1/4

To add these fractions, you need to find a common denominator. In this case, the least common denominator (LCD) is 12.

To make the first fraction have a denominator of 12, multiply the numerator and denominator by 4:
2/3 * 4/4 = 8/12

To make the second fraction have a denominator of 12, multiply the numerator and denominator by 3:
1/4 * 3/3 = 3/12

Now that both fractions have a denominator of 12, you can add them:
8/12 + 3/12 = 11/12

So, 2/3 + 1/4 = 11/12.
