Step-by-step explanation: To add mixed numbers, first add the fractions. To add unlike fractions such as 2/8 + 1/3, first find a common denominator. The common denominator of 8 and 3 is simply the least common multiple of 8 and 3 which is 24.

To get 24 in the denominator of 2/8, we multiply the numerator and denominator by 3 to get the equivalent fraction 6/24.

To get 24 in the denominator of 1/3, we multiply the numerator and denominator by 8 to get the equivalent fraction 8/24.

Now, we have to deal with adding mixed numbers. To add mixed numbers, we will first need to add the fractions. In this case, we have 6/24 + 8/24 which is 14/24.

Now, we have to add the whole numbers. In this case, we have 3 + 1 which gives us 4. Notice that we can reduce our fraction by dividing both the numerator and denominator by 2 to get 7/12.

Therefore, our answer is 4 and 7/12.
