Introduction

In this article, we will explore the concept of ratios and proportions in mathematics, specifically in the context of the weights of three boxes. We will use the given ratio of 3:2:1 and the weight of the lightest box to determine the weights of all three boxes.

Understanding the Ratio

A ratio is a way of comparing two or more quantities by division. In this case, the ratio of the weights of the three boxes is 3:2:1. This means that the weight of the heaviest box is 3 times the weight of the lightest box, the weight of the middle box is 2 times the weight of the lightest box, and the weight of the lightest box is 1 time its own weight.

Given Information

We are given that the lightest box weighs 10 kg. We can use this information to find the weights of the other two boxes.

Finding the Weights of the Boxes

Let's start by finding the weight of the middle box. Since the ratio of the weights of the three boxes is 3:2:1, the weight of the middle box is 2 times the weight of the lightest box. Therefore, the weight of the middle box is 2 x 10 kg = 20 kg.

Next, let's find the weight of the heaviest box. Since the ratio of the weights of the three boxes is 3:2:1, the weight of the heaviest box is 3 times the weight of the lightest box. Therefore, the weight of the heaviest box is 3 x 10 kg = 30 kg.

Conclusion

In conclusion, the weights of the three boxes are 10 kg, 20 kg, and 30 kg. We used the given ratio of 3:2:1 and the weight of the lightest box to determine the weights of all three boxes.

Example Use Case

This concept can be applied to real-life scenarios where we need to compare the weights of different objects. For example, in a warehouse, we may need to compare the weights of different boxes to determine which ones are the heaviest or lightest.

Tips and Tricks

When working with ratios, make sure to understand the concept of proportionality.
Use the given information to find the unknown quantities.
Check your work by plugging in the values to ensure that they are consistent with the given ratio.

Common Mistakes

Failing to understand the concept of proportionality.
Not using the given information to find the unknown quantities.
Not checking the work to ensure that it is consistent with the given ratio.

Real-World Applications

This concept has many real-world applications, including:

Warehouse management: In a warehouse, we may need to compare the weights of different boxes to determine which ones are the heaviest or lightest.
Supply chain management: In a supply chain, we may need to compare the weights of different packages to determine which ones are the heaviest or lightest.
Engineering: In engineering, we may need to compare the weights of different components to determine which ones are the heaviest or lightest.

Conclusion

In conclusion, the ratio of the weights of three boxes is 3:2:1, and the lightest box weighs 10 kg. We used the given ratio and the weight of the lightest box to determine the weights of all three boxes. This concept has many real-world applications, including warehouse management, supply chain management, and engineering.

Final Answer

The weights of the three boxes are 10 kg, 20 kg, and 30 kg.

Weight of the Lightest Box

10 kg

Weight of the Middle Box

20 kg

Weight of the Heaviest Box

30 kg

Introduction

In our previous article, we explored the concept of ratios and proportions in mathematics, specifically in the context of the weights of three boxes. We used the given ratio of 3:2:1 and the weight of the lightest box to determine the weights of all three boxes. In this article, we will answer some frequently asked questions related to this concept.

Q&A

Q: What is the ratio of the weights of the three boxes?

A: The ratio of the weights of the three boxes is 3:2:1.

Q: What is the weight of the lightest box?

A: The weight of the lightest box is 10 kg.

Q: How do I find the weight of the middle box?

A: To find the weight of the middle box, you need to multiply the weight of the lightest box by 2. In this case, the weight of the middle box is 2 x 10 kg = 20 kg.

Q: How do I find the weight of the heaviest box?

A: To find the weight of the heaviest box, you need to multiply the weight of the lightest box by 3. In this case, the weight of the heaviest box is 3 x 10 kg = 30 kg.

Q: What if the ratio of the weights of the three boxes is different?

A: If the ratio of the weights of the three boxes is different, you need to adjust the calculation accordingly. For example, if the ratio is 4:3:2, you need to multiply the weight of the lightest box by 4 to find the weight of the heaviest box, by 3 to find the weight of the middle box, and by 2 to find the weight of the lightest box.

Q: Can I use this concept to compare the weights of different objects?

A: Yes, you can use this concept to compare the weights of different objects. For example, in a warehouse, you can use this concept to compare the weights of different boxes to determine which ones are the heaviest or lightest.
