Equivalent fractions are fractions that have the same value, but may appear different due to the presence of different numerators and denominators. In this article, we will explore which fraction is equivalent to $\frac{8}{-13}$ .

What are Equivalent Fractions?

Equivalent fractions are fractions that have the same value, but may appear different due to the presence of different numerators and denominators. For example, $\frac{1}{2}$ and $\frac{2}{4}$ are equivalent fractions because they have the same value, but the numerators and denominators are different.

Properties of Equivalent Fractions

To determine if two fractions are equivalent, we need to check if they have the same value. We can do this by multiplying the numerator and denominator of one fraction by the same number. If the resulting fraction is equal to the other fraction, then the two fractions are equivalent.

Finding Equivalent Fractions

To find an equivalent fraction of $\frac{8}{-13}$ , we need to multiply the numerator and denominator by the same number. Let's try multiplying the numerator and denominator by -1.

$\frac{8}{-13} \times \frac{-1}{-1} = \frac{-8}{13}$

As we can see, the resulting fraction is $-\frac{8}{13}$ . Therefore, $-\frac{8}{13}$ is an equivalent fraction of $\frac{8}{-13}$ .

Analyzing the Options

Now that we have found an equivalent fraction of $\frac{8}{-13}$ , let's analyze the options.

A. $\frac{13}{8}$ : This fraction is not equivalent to $\frac{8}{-13}$ because the numerator and denominator are different.

B. $\frac{-13}{8}$ : This fraction is not equivalent to $\frac{8}{-13}$ because the numerator and denominator are different.

C. $\frac{-8}{-13}$ : This fraction is not equivalent to $\frac{8}{-13}$ because the numerator and denominator are different.

D. $-\frac{8}{13}$ : This fraction is equivalent to $\frac{8}{-13}$ because the numerator and denominator are the same, but the sign is different.

Conclusion

In conclusion, the equivalent fraction of $\frac{8}{-13}$ is $-\frac{8}{13}$ . This fraction has the same value as $\frac{8}{-13}$ , but the numerator and denominator are different.

Final Answer

The final answer is D. $-\frac{8}{13}$ .

Additional Tips and Tricks

When working with equivalent fractions, it's essential to remember that the numerator and denominator can be multiplied or divided by the same number.
To find an equivalent fraction, multiply the numerator and denominator by the same number.
When analyzing options, make sure to check if the numerator and denominator are the same, but the sign is different.

Common Mistakes to Avoid

Don't confuse equivalent fractions with similar fractions. Similar fractions have the same numerator and denominator, but the sign is different.
Don't forget to multiply the numerator and denominator by the same number when finding an equivalent fraction.
Don't assume that a fraction is equivalent just because the numerator and denominator are the same. Make sure to check if the sign is different.

Real-World Applications

Equivalent fractions have many real-world applications. For example, in cooking, equivalent fractions can be used to measure ingredients. In finance, equivalent fractions can be used to calculate interest rates. In science, equivalent fractions can be used to calculate the volume of a liquid.
