This image contains several math exercises related to fractions. Let me help break down and explain each of the questions based on what is visible.

### Exercise Breakdown:

**23. Number Line with Fractions:**
- The task asks to draw a number line and mark the fractions: \( \frac{1}{2}, \frac{1}{4}, -\frac{1}{4}, -\frac{3}{4} \). Additionally, you're asked to mark another fraction represented by one of the points.

**24. Change Fractions to Equivalent Fractions (with denominator 100):**
- Here, you need to convert each fraction to an equivalent fraction with a denominator of 100.
  - Examples:
    - \( \frac{1}{2} = \frac{50}{100} \)
    - \( \frac{2}{5} = \frac{40}{100} \)

**25. Write Three Fractions Equal to \( \frac{6}{12} \) with a Denominator Less than 12:**
- Find three fractions that are equivalent to \( \frac{6}{12} \) (which is simplified to \( \frac{1}{2} \)) and have denominators less than 12.

**26. Mixed Numbers to Improper Fractions:**
- Convert the given mixed numbers to improper fractions. For example:
  - \( 3 \frac{1}{5} = \frac{16}{5} \)
  - \( 2 \frac{1}{4} = \frac{9}{4} \)

**27. Improper Fractions to Mixed Numbers:**
- In this exercise, the task is reversed: convert improper fractions to mixed numbers. For instance:
  - \( \frac{7}{2} = 3 \frac{1}{2} \)

**28. Simplify Fractions to Irreducible Form:**
- The fractions given need to be simplified to their simplest form. For example:
  - \( \frac{6}{9} = \frac{2}{3} \)

**29. Laima's Fraction Puzzle:**
- This is a word problem: Laima came up with a fraction, multiplied both the numerator and denominator by 8, then divided them by 5. The resulting fraction is \( \frac{16}{24} \). You're tasked with figuring out the original fraction.

**30. Pizza Puzzle:**
- The last task describes a scenario where you bake a pizza and are asked to figure out how to divide it evenly into 8 equal parts using only three straight cuts. This is more of a geometric puzzle.

Would you like me to go into detail on any specific problem or provide the solutions for each one?

Here are 5 related questions to expand on this topic:
1. How can you convert between improper fractions and mixed numbers?
2. What steps should you follow to simplify fractions?
3. How do you find equivalent fractions with a specific denominator?
4. What is the quickest way to place fractions accurately on a number line?
5. What geometric principles help solve cutting puzzles like the pizza problem?

**Tip:** When simplifying fractions, always divide both the numerator and denominator by their greatest common divisor (GCD).
