Introduction

When it comes to planting wildflowers, understanding the coverage area of the seeds is crucial to ensure a beautiful and lush display. A label on a $$1 \frac{1}{2}$$ pound bag of wildflower seeds states that it will cover an area of 375 square feet. But what if you only need to cover a smaller area? Can you determine the number of square feet that 1 pound of wildflower seeds will cover? In this article, we will explore this question and provide a step-by-step solution.

Understanding the Problem

The problem states that a $$1 \frac{1}{2}$$ pound bag of wildflower seeds will cover an area of 375 square feet. To find the number of square feet that 1 pound of wildflower seeds will cover, we need to set up a proportion. Let's assume that x represents the number of square feet that 1 pound of wildflower seeds will cover.

Setting Up the Proportion

We can set up a proportion using the information given in the problem:

\frac{1 \frac{1}{2} \text{ pounds}}{375 \text{ square feet}} = \frac{1 \text{ pound}}{x \text{ square feet}}

To simplify the proportion, we can convert the mixed number $$1 \frac{1}{2}$$ to an improper fraction:

\frac{3}{2} \text{ pounds}

Now, we can rewrite the proportion:

\frac{\frac{3}{2} \text{ pounds}}{375 \text{ square feet}} = \frac{1 \text{ pound}}{x \text{ square feet}}

Solving the Proportion

To solve the proportion, we can cross-multiply:

\frac{3}{2} \text{ pounds} \cdot x \text{ square feet} = 1 \text{ pound} \cdot 375 \text{ square feet}

Simplifying the equation, we get:

\frac{3}{2}x = 375

To solve for x, we can multiply both sides of the equation by $$\frac{2}{3}$$:

x = 375 \cdot \frac{2}{3}

Simplifying the expression, we get:

x = 250

Conclusion

Therefore, 1 pound of wildflower seeds will cover an area of 250 square feet.

Understanding the Concept of Proportional Relationships

The concept of proportional relationships is a fundamental idea in mathematics. It involves understanding that two quantities are related in a specific way, and that a change in one quantity will result in a corresponding change in the other quantity. In this case, the proportionality between the weight of the wildflower seeds and the area they cover is a key concept.

Real-World Applications of Proportional Relationships

Proportional relationships have many real-world applications. For example, in engineering, proportional relationships are used to design and build structures that can withstand various loads and stresses. In finance, proportional relationships are used to calculate interest rates and investment returns. In science, proportional relationships are used to model and predict the behavior of complex systems.

Tips for Solving Proportional Relationships

When solving proportional relationships, it's essential to follow these tips:

Read the problem carefully: Make sure you understand what the problem is asking for.
Set up a proportion: Use the information given in the problem to set up a proportion.
Simplify the proportion: Simplify the proportion by canceling out any common factors.
Cross-multiply: Cross-multiply to solve for the unknown quantity.
Check your answer: Check your answer to make sure it makes sense in the context of the problem.

Introduction

In our previous article, we explored the concept of proportional relationships and how it can be applied to understand the coverage area of wildflower seeds. We set up a proportion to determine the number of square feet that 1 pound of wildflower seeds will cover. In this article, we will answer some frequently asked questions related to this topic.

Q&A

Q: What is the relationship between the weight of wildflower seeds and the area they cover?

A: The relationship between the weight of wildflower seeds and the area they cover is proportional. This means that if you increase the weight of the seeds, the area they cover will also increase proportionally.

Q: How do I set up a proportion to solve this problem?

A: To set up a proportion, you need to identify the two quantities that are related. In this case, the two quantities are the weight of the wildflower seeds and the area they cover. You can then set up a proportion using the following format:

\frac{\text{weight of seeds}}{\text{area covered}} = \frac{\text{weight of seeds}}{\text{area covered}}

Q: What is the formula for solving a proportion?

A: The formula for solving a proportion is:

\frac{a}{b} = \frac{c}{d}

ad = bc

d = \frac{bc}{a}

Q: How do I simplify a proportion?

A: To simplify a proportion, you can cancel out any common factors between the numerator and the denominator. For example, if you have the proportion:

\frac{6}{8} = \frac{3}{4}

You can simplify it by canceling out the common factor of 2:

\frac{3}{4} = \frac{3}{4}

Q: What is the difference between a proportion and a ratio?

A: A proportion is a statement that two ratios are equal, while a ratio is a comparison of two quantities. For example, the statement:

\frac{2}{3} = \frac{4}{6}

is a proportion, while the statement:

\frac{2}{3}

is a ratio.

Q: How do I use a proportion to solve a real-world problem?

A: To use a proportion to solve a real-world problem, you need to identify the two quantities that are related and set up a proportion using the following format:

\frac{\text{quantity 1}}{\text{quantity 2}} = \frac{\text{quantity 3}}{\text{quantity 4}}

You can then solve for the unknown quantity by cross-multiplying and simplifying the proportion.

Conclusion

In conclusion, the label on a bag of wildflower seeds states that it will cover an area of 375 square feet. By setting up a proportion and solving for the unknown quantity, we can determine that 1 pound of wildflower seeds will cover an area of 250 square feet. This problem illustrates the concept of proportional relationships and provides a real-world application of this mathematical concept.
