What are Proportions?

A proportion is a mathematical statement that shows the equality of two ratios. It is often written in the form of a fraction, where the two fractions have the same value. For example, the proportion $\frac{3}{4}=\frac{6}{8}$ states that the ratio of 3 to 4 is equal to the ratio of 6 to 8.

Identifying Extremes in a Proportion

In a proportion, the extremes are the outer numbers, while the means are the inner numbers. To identify the extremes, we need to look at the two fractions and find the numbers that are not in the middle. In the proportion $\frac{3}{4}=\frac{6}{8}$ , the extremes are 3 and 8.

Why are 3 and 8 the Extremes?

The numbers 3 and 8 are the extremes because they are the outer numbers in the proportion. The number 3 is the first number in the first fraction, and the number 8 is the second number in the second fraction. The numbers 4 and 6 are the means because they are the inner numbers in the proportion.

How to Identify Extremes in a Proportion

To identify the extremes in a proportion, follow these steps:

Write the proportion as two fractions.
Look at the two fractions and find the numbers that are not in the middle.
The numbers that are not in the middle are the extremes.

Example 1: Identifying Extremes in a Proportion

Find the extremes in the proportion $\frac{2}{3}=\frac{4}{6}$ .

To identify the extremes, follow the steps above:

Write the proportion as two fractions: $\frac{2}{3}=\frac{4}{6}$ .
Look at the two fractions and find the numbers that are not in the middle.
The numbers that are not in the middle are the extremes. In this case, the extremes are 2 and 6.

Example 2: Identifying Extremes in a Proportion

Find the extremes in the proportion $\frac{5}{6}=\frac{10}{12}$ .

To identify the extremes, follow the steps above:

Write the proportion as two fractions: $\frac{5}{6}=\frac{10}{12}$ .
Look at the two fractions and find the numbers that are not in the middle.
The numbers that are not in the middle are the extremes. In this case, the extremes are 5 and 12.

Conclusion

In conclusion, the extremes in a proportion are the outer numbers, while the means are the inner numbers. To identify the extremes, follow the steps above and look at the two fractions to find the numbers that are not in the middle. The numbers that are not in the middle are the extremes.

Answer

The correct answer is A. 3 and 8.

Final Thoughts

$Understanding proportions and identifying extremes is an important concept in mathematics. By following the steps above and looking at the two fractions, you can easily identify the extremes in a proportion. This concept is used in many areas of mathematics, including algebra and geometry.<br/> **Frequently Asked Questions: Understanding Proportions and Identifying Extremes**$

Q: What is a proportion?

A: A proportion is a mathematical statement that shows the equality of two ratios. It is often written in the form of a fraction, where the two fractions have the same value.

Q: How do I identify the extremes in a proportion?

A: To identify the extremes in a proportion, follow these steps:

Write the proportion as two fractions.
Look at the two fractions and find the numbers that are not in the middle.
The numbers that are not in the middle are the extremes.

Q: What are the means in a proportion?

A: The means in a proportion are the inner numbers. In the proportion $\frac{3}{4}=\frac{6}{8}$ , the means are 4 and 6.

Q: Why are the means important in a proportion?

A: The means are important in a proportion because they help to identify the extremes. By finding the means, you can easily identify the extremes in a proportion.

Q: Can you give an example of a proportion with the extremes and means identified?

A: Yes, here is an example of a proportion with the extremes and means identified:

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

In this proportion, the extremes are 2 and 6, and the means are 3 and 4.

Q: How do I use proportions in real-life situations?

A: Proportions are used in many real-life situations, such as:

Cooking: When a recipe calls for a certain ratio of ingredients, you can use proportions to ensure that you have the right amount of each ingredient.
Building: When building a structure, you may need to use proportions to ensure that the different parts of the structure are in the correct ratio.
Finance: When investing in stocks or bonds, you may need to use proportions to determine the return on investment.

Q: What are some common mistakes to avoid when working with proportions?

A: Some common mistakes to avoid when working with proportions include:

Not simplifying the fractions before comparing them.

Not using proportions to solve real-life problems.

Q: How can I practice working with proportions?

A: You can practice working with proportions by:

Using online resources, such as math websites or apps.
Working with a tutor or teacher.
Practicing with real-life problems, such as cooking or building.

Q: What are some advanced concepts related to proportions?

A: Some advanced concepts related to proportions include:

Similar triangles: When two triangles have the same shape but not necessarily the same size, they are similar.
Ratios: When two or more numbers are in a certain ratio, they are said to be in proportion.
Percentages: When a number is expressed as a percentage of another number, it is said to be in proportion.
