To solve \(6 \frac{5}{12} + 3 \frac{3}{4}\), follow these steps:

### Step 1: Convert the mixed numbers to improper fractions
1. Convert \(6 \frac{5}{12}\):
   \[
   6 \frac{5}{12} = \frac{6 \times 12 + 5}{12} = \frac{72 + 5}{12} = \frac{77}{12}
   \]
   
2. Convert \(3 \frac{3}{4}\):
   \[
   3 \frac{3}{4} = \frac{3 \times 4 + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4}
   \]

### Step 2: Find a common denominator
The least common denominator (LCD) of 12 and 4 is 12. Rewrite \(\frac{15}{4}\) with denominator 12:
\[
\frac{15}{4} = \frac{15 \times 3}{4 \times 3} = \frac{45}{12}
\]

### Step 3: Add the fractions
Now add \(\frac{77}{12} + \frac{45}{12}\):
\[
\frac{77}{12} + \frac{45}{12} = \frac{77 + 45}{12} = \frac{122}{12}
\]

### Step 4: Simplify the result
Divide the numerator and the denominator by their greatest common divisor (GCD), which is 2:
\[
\frac{122}{12} = \frac{122 \div 2}{12 \div 2} = \frac{61}{6}
\]

### Step 5: Convert the improper fraction back to a mixed number
\[
\frac{61}{6} = 10 \frac{1}{6}
\]

Thus, \(6 \frac{5}{12} + 3 \frac{3}{4} = 10 \frac{1}{6}\).
