Introduction

Fractions are a fundamental concept in mathematics, representing a part of a whole. In this article, we will delve into the world of fractions and explore the concept of equivalent ratios. We will examine four pairs of fractions and determine whether they represent the same ratio.

What are Equivalent Ratios?

Equivalent ratios are fractions that have the same value, even if they are expressed differently. In other words, two fractions are equivalent if they can be simplified to the same value. For example, the fractions $\frac{1}{2}$ and $\frac{2}{4}$ are equivalent because they can be simplified to the same value, $\frac{1}{2}$ .

Pair A: $\frac{2}{1}$ and $\frac{12}{4}$

To determine whether these two fractions represent the same ratio, we need to simplify them. The fraction $\frac{2}{1}$ is already in its simplest form, so we can leave it as is. The fraction $\frac{12}{4}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 4. This gives us $\frac{3}{1}$ .

As we can see, the two fractions are not equivalent. The fraction $\frac{2}{1}$ is equal to 2, while the fraction $\frac{3}{1}$ is equal to 3. Therefore, pair A does not represent the same ratio.

Pair B: $\frac{1}{6}$ and $\frac{3}{2}$

To determine whether these two fractions represent the same ratio, we need to simplify them. The fraction $\frac{1}{6}$ is already in its simplest form, so we can leave it as is. The fraction $\frac{3}{2}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1. This gives us $\frac{3}{2}$ .

As we can see, the two fractions are not equivalent. The fraction $\frac{1}{6}$ is equal to 0.17, while the fraction $\frac{3}{2}$ is equal to 1.5. Therefore, pair B does not represent the same ratio.

Pair C: $\frac{1}{2}$ and $\frac{3}{6}$

To determine whether these two fractions represent the same ratio, we need to simplify them. The fraction $\frac{1}{2}$ is already in its simplest form, so we can leave it as is. The fraction $\frac{3}{6}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3. This gives us $\frac{1}{2}$ .

As we can see, the two fractions are equivalent. They can be simplified to the same value, $\frac{1}{2}$ . Therefore, pair C represents the same ratio.

Pair D: $\frac{1}{3}$ and $\frac{2}{6}$

To determine whether these two fractions represent the same ratio, we need to simplify them. The fraction $\frac{1}{3}$ is already in its simplest form, so we can leave it as is. The fraction $\frac{2}{6}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This gives us $\frac{1}{3}$ .

As we can see, the two fractions are equivalent. They can be simplified to the same value, $\frac{1}{3}$ . Therefore, pair D represents the same ratio.

Conclusion

In conclusion, we have examined four pairs of fractions and determined whether they represent the same ratio. We found that pair C and pair D represent the same ratio, while pair A and pair B do not. This demonstrates the importance of simplifying fractions to determine whether they are equivalent.

Tips for Simplifying Fractions

Simplifying fractions can be a challenging task, but there are some tips that can make it easier. Here are a few tips to keep in mind:

Find the greatest common divisor (GCD): The GCD is the largest number that divides both the numerator and the denominator. You can find the GCD by listing the factors of both numbers and finding the largest common factor.
Divide both the numerator and the denominator by the GCD: Once you have found the GCD, you can simplify the fraction by dividing both the numerator and the denominator by the GCD.
Check for equivalent ratios: After simplifying the fraction, you can check whether it is equivalent to another fraction by dividing both the numerator and the denominator by their greatest common divisor.

By following these tips, you can simplify fractions and determine whether they represent the same ratio.

Real-World Applications of Equivalent Ratios

Equivalent ratios have many real-world applications. Here are a few examples:

Cooking: When cooking, you may need to scale up or down a recipe. Equivalent ratios can help you do this by allowing you to multiply or divide the ingredients by the same factor.
Building: When building a structure, you may need to calculate the area or volume of a shape. Equivalent ratios can help you do this by allowing you to simplify the fraction and calculate the area or volume more easily.
Science: In science, equivalent ratios can be used to calculate the concentration of a solution or the amount of a substance in a mixture.

By understanding equivalent ratios, you can apply mathematical concepts to real-world problems and make more informed decisions.

Conclusion

Q: What is an equivalent ratio?

A: An equivalent ratio is a fraction that has the same value as another fraction, even if they are expressed differently. In other words, two fractions are equivalent if they can be simplified to the same value.

Q: How do I determine if two fractions are equivalent?

A: To determine if two fractions are equivalent, you need to simplify them by dividing both the numerator and the denominator by their greatest common divisor (GCD). If the simplified fractions are the same, then the original fractions are equivalent.

Q: What is the greatest common divisor (GCD)?

A: The greatest common divisor (GCD) is the largest number that divides both the numerator and the denominator of a fraction. You can find the GCD by listing the factors of both numbers and finding the largest common factor.

Q: How do I find the GCD of two numbers?

A: To find the GCD of two numbers, you can use the following steps:

List the factors of both numbers.
Find the largest common factor.
The largest common factor is the GCD.

Q: What are some real-world applications of equivalent ratios?

A: Equivalent ratios have many real-world applications, including:

Cooking: When cooking, you may need to scale up or down a recipe. Equivalent ratios can help you do this by allowing you to multiply or divide the ingredients by the same factor.
Building: When building a structure, you may need to calculate the area or volume of a shape. Equivalent ratios can help you do this by allowing you to simplify the fraction and calculate the area or volume more easily.
Science: In science, equivalent ratios can be used to calculate the concentration of a solution or the amount of a substance in a mixture.

Q: How do I simplify a fraction?

A: To simplify a fraction, you need to divide both the numerator and the denominator by their greatest common divisor (GCD). If the GCD is 1, then the fraction is already simplified.

Q: What is the difference between equivalent ratios and proportional ratios?

A: Equivalent ratios are fractions that have the same value, even if they are expressed differently. Proportional ratios are fractions that have the same ratio, but may not have the same value. For example, the fractions $\frac{1}{2}$ and $\frac{2}{4}$ are equivalent, but the fractions $\frac{1}{2}$ and $\frac{3}{6}$ are proportional.

Q: How do I determine if two fractions are proportional?

A: To determine if two fractions are proportional, you need to check if they have the same ratio. You can do this by dividing both fractions by their greatest common divisor (GCD) and checking if the resulting fractions are equal.

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

A: Some common mistakes to avoid when working with equivalent ratios include:

Not simplifying fractions before comparing them.
Not finding the greatest common divisor (GCD) of two numbers.
Not checking if two fractions are proportional before comparing them.

Q: How do I apply equivalent ratios to real-world problems?

A: To apply equivalent ratios to real-world problems, you need to:

Identify the problem and the relevant information.
Simplify the fractions involved.
Check if the fractions are equivalent or proportional.
Use the equivalent or proportional fractions to solve the problem.

By following these steps, you can apply equivalent ratios to real-world problems and make more informed decisions.
