I see that you've uploaded a worksheet related to adding and subtracting mixed fractions. I will guide you through solving these problems step by step.

Let's start with problem 1 as an example:

**1. \( 2 \frac{1}{5} + 1 \frac{3}{4} \)**

### Step-by-step solution:

1. Convert both mixed numbers to improper fractions:
   - \( 2 \frac{1}{5} = \frac{11}{5} \) (because \( 2 \times 5 + 1 = 11 \))
   - \( 1 \frac{3}{4} = \frac{7}{4} \) (because \( 1 \times 4 + 3 = 7 \))

2. Find a common denominator for \( \frac{11}{5} \) and \( \frac{7}{4} \). The least common denominator (LCD) is 20.

   - \( \frac{11}{5} = \frac{44}{20} \)
   - \( \frac{7}{4} = \frac{35}{20} \)

3. Add the fractions:
   - \( \frac{44}{20} + \frac{35}{20} = \frac{79}{20} \)

4. Convert \( \frac{79}{20} \) back to a mixed number:
   - \( \frac{79}{20} = 3 \frac{19}{20} \)

So, the solution to \( 2 \frac{1}{5} + 1 \frac{3}{4} \) is \( 3 \frac{19}{20} \).
