The image you uploaded shows problems involving the multiplication of regular fractions with mixed numbers ("pecahan biasa x pecahan campuran").

Let's solve the problems shown in the image one by one.

1. **\(\frac{2}{5} \times 5 \frac{2}{3}\)**:
   - Convert \(5 \frac{2}{3}\) to an improper fraction:
     \[
     5 \frac{2}{3} = \frac{5 \times 3 + 2}{3} = \frac{17}{3}
     \]
   - Now multiply:
     \[
     \frac{2}{5} \times \frac{17}{3} = \frac{2 \times 17}{5 \times 3} = \frac{34}{15}
     \]
   - This is already in its simplest form as an improper fraction, but you can also write it as:
     \[
     2 \frac{4}{15}
     \]

2. **\(\frac{5}{6} \times 2 \frac{1}{2}\)**:
   - Convert \(2 \frac{1}{2}\) to an improper fraction:
     \[
     2 \frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2}
     \]
   - Now multiply:
     \[
     \frac{5}{6} \times \frac{5}{2} = \frac{5 \times 5}{6 \times 2} = \frac{25}{12}
     \]
   - This is also an improper fraction, and can be written as:
     \[
     2 \frac{1}{12}
     \]

3. **\(\frac{4}{5} \times 2 \frac{2}{4}\)**:
   - Convert \(2 \frac{2}{4}\) to an improper fraction. Since \(\frac{2}{4} = \frac{1}{2}\), we have:
     \[
     2 \frac{2}{4} = 2 \frac{1}{2} = \frac{5}{2}
     \]
   - Now multiply:
     \[
     \frac{4}{5} \times \frac{5}{2} = \frac{4 \times 5}{5 \times 2} = \frac{20}{10} = 2
     \]

4. **\(3 \frac{1}{3} \times \frac{3}{8}\)**:
   - Convert \(3 \frac{1}{3}\) to an improper fraction:
     \[
     3 \frac{1}{3} = \frac{3 \times 3 + 1}{3} = \frac{10}{3}
     \]
   - Now multiply:
     \[
     \frac{10}{3} \times \frac{3}{8} = \frac{10 \times 3}{3 \times 8} = \frac{30}{24} = \frac{5}{4} = 1 \frac{1}{4}
     \]

5. **\(4 \frac{4}{5} \times \frac{5}{6}\)**:
   - Convert \(4 \frac{4}{5}\) to an improper fraction:
     \[
     4 \frac{4}{5} = \frac{4 \times 5 + 4}{5} = \frac{24}{5}
     \]
   - Now multiply:
     \[
     \frac{24}{5} \times \frac{5}{6} = \frac{24 \times 5}{5 \times 6} = \frac{120}{30} = 4
     \]

These are the solutions to all the problems listed.
