This is a mathematics worksheet packet designed for students to practice various concepts related to percentages. Despite the title including "Ratio," the content focuses almost exclusively on percentage calculations and conversions. The document includes both blank worksheets and a complete answer key.

The packet is divided into four main sections:

1. Percent - Basic (Pages 1–20)

• Content: extensive drills asking students to calculate a specific percentage of a number.
• Examples: "10% of 40 =", "25% of 82 =", "50% of 13".
• Difficulty: These start with standard percentages (10%, 20%, 25%, 50%) and move toward slightly more varied numbers (3%, 4%, 15%).

2. Word Problems - Percent (Pages 21–27)

• Content: Real-world scenario problems that require applying percentage formulas.
• Topics Covered:
  • Calculating sales tax on purchases (jackets, bicycles).
  • Determining income tax.
  • Calculating population demographics (e.g., percentage of boys in a school).
  • Increasing or decreasing numbers by a certain percentage.
  • Finding the remaining amount after a percentage is given away (e.g., baseball cards).

3. Percent - Advanced (Pages 28–33)

• Content: Calculation drills similar to the "Basic" section but with more complex and random numbers.
• Examples: "42% of 6 =", "87% of 493 =", "13% of 535".

4. Percent and Decimals (Pages 34–39)

• Content: Exercises focused on converting percentages into decimal form.

5. Answer Key (Pages 40–78)

• The second half of the PDF contains the solutions for every problem listed in the previous sections, filled in red next to the original questions.
