Topic

Solving Equations

Description

This math example focuses on solving percent equations, specifically asking "What is 30% of 9?" The solution involves converting 30% to its decimal form, 0.3, and then multiplying it by 9 to get the result of 2.7. This example introduces a larger percentage, demonstrating how the method applies consistently across various percentage values.

Solving equations with percents is a crucial skill in mathematics that finds applications in numerous real-world scenarios, from calculating discounts to understanding statistical data. These examples help students grasp the fundamental concept of converting percentages to decimals and applying them to given values. This understanding forms the foundation for more complex mathematical operations and problem-solving in various fields.

Providing multiple worked-out examples is essential for students to fully comprehend this concept. Each new example reinforces the process while introducing different percentage values and base numbers. This approach allows students to recognize patterns, adapt their problem-solving strategies, and build confidence in handling diverse percentage-based calculations, preparing them for more advanced mathematical challenges.

Teacher Script: "Let's look at our next example. We need to find 30% of 9. What's our first step? Right, we convert the percentage to a decimal. So, 30% becomes 0.3. Now, we multiply this by our base number, 9. Can anyone tell me what 0.3 × 9 equals? Great job, it's 2.7. Notice how we're using the same method, but with a larger percentage this time. This shows that our approach works consistently, regardless of the size of the percentage we're working with. Remember, the key is always to convert the percentage to a decimal first, then multiply."
