Understanding the Original Scale

The Daly family has a blueprint for their living room with a scale of 2 inches = 3 feet. This means that every 2 inches on the blueprint represents 3 feet in real life. To understand the original scale, we need to calculate the ratio of inches to feet.

Original Scale Ratio: 2 inches = 3 feet

To find the ratio, we can divide the number of feet by the number of inches:

Original Scale Ratio: 3 feet / 2 inches = 1.5 feet/inch

Understanding the New Scale

The family wants to use a new scale of 1 inch = 6 feet. This means that every 1 inch on the new blueprint represents 6 feet in real life. To understand the new scale, we need to calculate the ratio of inches to feet.

New Scale Ratio: 1 inch = 6 feet

To find the ratio, we can divide the number of feet by the number of inches:

New Scale Ratio: 6 feet / 1 inch = 6 feet/inch

Converting the Original Scale to the New Scale

To convert the original scale to the new scale, we need to find the ratio of the new scale to the original scale. We can do this by dividing the new scale ratio by the original scale ratio:

Conversion Ratio: (6 feet/inch) / (1.5 feet/inch) = 4

This means that every 1 inch on the original blueprint represents 4 inches on the new blueprint.

Finding the Width of the Living Room on the New Blueprint

Let's assume that the width of the living room on the original blueprint is x inches. We can use the conversion ratio to find the width of the living room on the new blueprint:

Width on the New Blueprint: x inches x 4 = 4x inches

Solving for the Width on the New Blueprint

Since we don't know the value of x, we can't find the exact width of the living room on the new blueprint. However, we can express the width in terms of x.

Width on the New Blueprint: 4x inches

Conclusion

The width of the living room on the new blueprint is 4x inches, where x is the width of the living room on the original blueprint.

Example

Let's say the width of the living room on the original blueprint is 12 inches. We can use the conversion ratio to find the width of the living room on the new blueprint:

Width on the New Blueprint: 12 inches x 4 = 48 inches

Therefore, the width of the living room on the new blueprint is 48 inches.

Real-World Applications

Scaling up or down is a common problem in architecture, engineering, and design. Architects and engineers need to create blueprints and models of buildings, bridges, and other structures that are proportional to the real-world structures. By understanding how to scale up or down, they can create accurate and detailed models that help them design and build complex structures.

Tips and Tricks

When scaling up or down, make sure to keep track of the ratios and proportions.
Use conversion ratios to find the new dimensions.
Double-check your calculations to ensure accuracy.

Common Mistakes

Failing to keep track of the ratios and proportions.
Not using conversion ratios to find the new dimensions.
Not double-checking calculations for accuracy.

Conclusion

Scaling up or down is a fundamental concept in mathematics and engineering. By understanding how to scale up or down, we can create accurate and detailed models of real-world structures. In this article, we explored the concept of scaling up or down and how to apply it to the Daly's living room blueprint. We also discussed real-world applications, tips and tricks, and common mistakes to avoid.

Frequently Asked Questions
