    Add the two mixed numbers:

       2 5/8 

    + 1 3/4

    ----------

    Get the same denominator for the fractions:

       2 5/8

    + 1 6/8 <--

    ---------- 

    Add the fractions:

       2 5/8

    + 1 6/8

    ----------

         11/8 <-- convert to 1 3/8

    Write down 3/8 and carry the 1:

       ₁

       2 5/8

    + 1 6/8

    ----------

          3/8

    Add the whole numbers:

       ₁

       2 5/8

    + 1 6/8

    ----------

       4 3/8

    So far we have:

    4 3/8 + (??) = 8

    To figure out the missing value, subtract 8 - 4 3/8

      8

    - 4 3/8

    ---------

    We need to borrow 1 from the 8 (which is the same as borrowing 8/8):

      7 8/8

    - 4 3/8

    ---------

    Subtract:

      7 8/8

    - 4 3/8

    ---------

      3 5/8

    Answer:

    The missing number is 3 5/8

    Double-check:

       2 5/8  

       1 6/8

    + 3 5/8

    ----------

         16/8 <-- convert to 2, write down nothing for the fraction and carry 2:

       ₂

       2 5/8

       1 6/8

    + 3 5/8 <-- This is the missing number

    ----------

       8
