### Evaluation of Mixed Numbers

This section aims to help you evaluate mixed numbers. Work through the following example to understand the process better.

#### Problem Statement:
Evaluate \( 2 \dfrac{1}{4} + \dfrac{5}{6} \).

#### Multiple Choice Answers:

- \( \boxed{2 \dfrac{3}{5}} \)
- \( \dfrac{37}{12} \)
- \( 3 \)

### Steps to Solve

1. **Convert the Mixed Number to an Improper Fraction:**

   First, convert \( 2 \dfrac{1}{4} \) to an improper fraction.
   
   \[
   2 \dfrac{1}{4} = \frac{2 \times 4 + 1}{4} = \frac{8 + 1}{4} = \frac{9}{4}
   \]

2. **Find a Common Denominator:**

   The given fractions now are \( \frac{9}{4} \) and \( \frac{5}{6} \). To add these fractions, you need a common denominator. The least common multiple of 4 and 6 is 12.
   
   Convert the fractions:
   
   \[
   \frac{9}{4} = \frac{9 \times 3}{4 \times 3} = \frac{27}{12}
   \]
   
   \[
   \frac{5}{6} = \frac{5 \times 2}{6 \times 2} = \frac{10}{12}
   \]

3. **Add the Fractions:**
   
   \[
   \frac{27}{12} + \frac{10}{12} = \frac{37}{12}
   \]

4. **Convert the Improper Fraction to a Mixed Number:**

   \[
   \frac{37}{12} = 3 \dfrac{1}{12}
   \]

### Conclusion:

Converting \( 2 \dfrac{1}{4} + \dfrac{5}{6} \) results in \( 3 \dfrac{1}{12} \). The correct answer is not listed in the multiple-choice options provided. 
There is an apparent error in the choices given. The selected choice \( \boxed{2 \dfrac{3}{5}} \) is not the correct answer
