Here are the solutions to the given problems:

1. \( \frac{3}{4} + \frac{3}{4} \):
   - The denominators are the same, so add the numerators.
   \[
   \frac{3}{4} + \frac{3}{4} = \frac{3+3}{4} = \frac{6}{4}
   \]
   Simplify \( \frac{6}{4} \):
   \[
   \frac{6}{4} = \frac{3}{2} = 1 \frac{1}{2}
   \]

2. \( \frac{4}{5} + \frac{2}{4} \):
   - Find the least common denominator (LCD). The LCD of 5 and 4 is 20.
   - Convert the fractions:
     \[
     \frac{4}{5} = \frac{16}{20}, \quad \frac{2}{4} = \frac{10}{20}
     \]
   - Add the fractions:
     \[
     \frac{16}{20} + \frac{10}{20} = \frac{26}{20}
     \]
   Simplify \( \frac{26}{20} \):
   \[
   \frac{26}{20} = \frac{13}{10} = 1 \frac{3}{10}
   \]

3. \( \frac{1}{5} + \frac{4}{5} \):
   - The denominators are the same, so add the numerators.
   \[
   \frac{1}{5} + \frac{4}{5} = \frac{1+4}{5} = \frac{5}{5} = 1
   \]

4. \( \frac{2}{4} + \frac{4}{8} \):
   - Simplify \( \frac{2}{4} = \frac{1}{2} \) and \( \frac{4}{8} = \frac{1}{2} \).
   - Add the simplified fractions:
     \[
     \frac{1}{2} + \frac{1}{2} = 1
     \]
