2/3+8 3/4

To add fractions, you need a common denominator. In this case, the common denominator can be found by multiplying the denominators together:

Common denominator = 3 * 4 = 12

Now, we adjust the fractions to have the common denominator:

2/3 + 8 3/4 = (2/3) * (4/4) + (8 3/4) * (3/3)
= 8/12 + 35/12

Next, we add the fractions:

8/12 + 35/12 = (8 + 35)/12
= 43/12

Therefore, 2/3 + 8 3/4 equals 43/12 or it can also be written as 3 7/12.
