5 1/2 + 5 1/? = 10 4/6

Converting mixed numbers to fractions:

If we observe carefully, we notice than both mixed numbers on the left start with 5 as whole number and their sum are the whole number of the result of the right

5 + 5 = 10

Therefore, just let's work with the fractions, this way:

1/2 + 1/? = 4/6

1/? = 4/6 - 1/2

1/? = 4/6 - 3/6

1/? = 1/6

The value of the missing number is 6, as denominator of the mixed number 5 1/6
