Description
This math example demonstrates solving percent equations by asking "What is 6.5% of 45.5?" The solution involves converting 6.5% to its decimal equivalent, 0.065, and then multiplying it by 45.5 to obtain the result of 2.9575. This example introduces both a decimal percentage and a decimal base number, adding complexity to the calculation.
Solving equations with percents is a fundamental skill in mathematics that has wide-ranging applications in finance, statistics, and everyday problem-solving. These examples help students understand the process of converting percentages to decimals and applying them to various numbers, including decimals. This skill is crucial for more advanced mathematical concepts and real-world scenarios where precise calculations are necessary.
The importance of presenting multiple worked-out examples cannot be overstated. Each new example reinforces the concept while introducing slight variations, such as decimal percentages or base numbers. This approach helps students recognize patterns, adapt their problem-solving strategies, and gain confidence in their ability to handle diverse scenarios involving percentages, preparing them for more complex mathematical challenges.
Teacher Script: "Now, let's tackle a slightly more complex example. We need to find 6.5% of 45.5. First, what do we do with the percentage? That's right, we convert it to a decimal. So, 6.5% becomes 0.065. Now, we multiply this by our base number, 45.5. Can anyone tell me what 0.065 × 45.5 equals? Excellent, it's 2.9575. Notice how we're still following the same steps, but now we're working with decimal percentages and decimal base numbers. This shows that our method is versatile and can handle various types of numbers."
