Understanding Fractions with a Common Denominator

When dealing with fractions, it's essential to understand the concept of a common denominator. A common denominator is the least common multiple (LCM) of the denominators of two or more fractions. It allows us to add, subtract, multiply, or divide fractions by making their denominators the same.

Finding the Least Common Multiple (LCM)

To find the LCM of two numbers, we need to list the multiples of each number and find the smallest multiple that is common to both. For example, the multiples of 8 are 8, 16, 24, 32, ... and the multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, ... . The smallest multiple that is common to both is 24.

Applying the Concept to the Given Fractions

Now, let's apply the concept to the given fractions: $\frac{6}{8}$ and $\frac{2}{3}$ . To find the common denominator, we need to find the LCM of 8 and 3, which is 24.

Converting the Fractions to Have a Common Denominator

To convert the fractions to have a common denominator, we need to multiply the numerator and denominator of each fraction by the necessary factor. For $\frac{6}{8}$ , we need to multiply the numerator and denominator by 3 to get $\frac{18}{24}$ . For $\frac{2}{3}$ , we need to multiply the numerator and denominator by 8 to get $\frac{16}{24}$ .

Comparing the Options

Now, let's compare the options:

A. $\frac{6}{8}$ and $\frac{7}{8}$

B. $\frac{18}{24}$ and $\frac{16}{24}$

C. $\frac{6}{8}$ and $\frac{2}{3}$

D. $\frac{18}{24}$ and $\frac{7}{8}$

Analyzing the Options

Option A is incorrect because the fractions do not have a common denominator. Option C is incorrect because the fractions do not have a common denominator. Option D is incorrect because the fractions do not have a common denominator.

Conclusion

The correct answer is option B: $\frac{18}{24}$ and $\frac{16}{24}$ . This is because the fractions have a common denominator of 24, which is the LCM of 8 and 3.

Why is it Important to Have a Common Denominator?

Having a common denominator is essential when working with fractions because it allows us to perform operations such as addition, subtraction, multiplication, and division. Without a common denominator, we cannot perform these operations, and the fractions become meaningless.

Real-World Applications

The concept of a common denominator has many real-world applications. For example, in finance, we often need to compare the interest rates of different loans or investments. In this case, we need to find the common denominator of the interest rates to make a fair comparison.

Conclusion

In conclusion, the correct answer is option B: $\frac{18}{24}$ and $\frac{16}{24}$ . This is because the fractions have a common denominator of 24, which is the LCM of 8 and 3. Having a common denominator is essential when working with fractions, and it has many real-world applications.
