To find Gary's brother's age, we need to subtract 3 7/12 from 8 3/4.
Converting the mixed numbers to improper fractions, we have: 8 3/4 = 35/4 and 3 7/12 = 43/12.
To subtract fractions, we need to find a common denominator. The smallest common multiple of 4 and 12 is 12.
Now, converting both fractions to have a denominator of 12, we have: 35/4 = 105/12 and 43/12.
Subtracting the fractions, we have: 105/12 - 43/12 = 62/12.
The fraction 62/12 can be simplified to 5 2/12 which equals to 5 1/6.
Therefore, Gary's brother is 5 1/6 years old. Answer: \boxed{C}.
