To solve the problem 5 1/2 - 1 3/7, we need to find a common denominator for the fractions.
The common denominator for 2 and 7 is 14.
Converting both fractions:
5 1/2 = 10/2 + 1/2 = 11/2
1 3/7 = 7/7 + 3/7 = 10/7
Now we can subtract:
11/2 - 10/7
Combining the fractions:
(11*7)/(2*7) - (10*2)/(7*2)
77/14 - 20/14 = 57/14
Therefore, the difference is 57/14.

Apologies for the previous incorrect response. Let's solve the problem correctly.
To subtract mixed fractions, we need to find a common denominator for the fractions. The common denominator for 2 and 7 is 14.
Converting both mixed fractions:
5 1/2 = 5 * 2/2 + 1/2 = 10/2 + 1/2 = 11/2
1 3/7 = 1 * 7/7 + 3/7 = 7/7 + 3/7 = 10/7
Now we can subtract:
11/2 - 10/7
To subtract fractions, we need to find a common denominator. In this case, the common denominator is 2 * 7 = 14.
Converting 11/2 to have a denominator of 14:
11/2 = 11 * 7/2 * 7 = 77/14
Now we can subtract:
77/14 - 10/7
Next, to subtract fractions, we need to have the same denominator. Since the denominators are already the same, we can just subtract the numerators:
77 - 10 = 67
Therefore, the answer is 67/14 or 4 11/14.
