Introduction

In mathematics, the absolute value of a number is its distance from zero on the number line. It is a measure of the magnitude or size of a number, without considering its direction or sign. In this article, we will focus on finding the absolute value of a fraction, specifically $\left|\frac{11}{5}\right|$ .

What is Absolute Value?

The absolute value of a number $x$ , denoted by $|x|$ , is defined as:

|x| = \begin{cases} x & \text{if } x \geq 0 \\ -x & \text{if } x < 0 \end{cases}

This means that if the number is positive or zero, its absolute value is the number itself. If the number is negative, its absolute value is the negative of the number.

Finding the Absolute Value of a Fraction

To find the absolute value of a fraction, we need to consider the numerator and denominator separately. The absolute value of a fraction $\frac{a}{b}$ is defined as:

\left|\frac{a}{b}\right| = \frac{|a|}{|b|}

In the case of $\left|\frac{11}{5}\right|$ , we have:

\left|\frac{11}{5}\right| = \frac{|11|}{|5|}

Calculating the Absolute Value

Now, let's calculate the absolute value of the numerator and denominator:

|11| = 11

|5| = 5

Substituting the Values

Substituting the values of the absolute values of the numerator and denominator into the formula, we get:

\left|\frac{11}{5}\right| = \frac{11}{5}

Conclusion

In conclusion, the absolute value of $\frac{11}{5}$ is $\frac{11}{5}$ . This is because the numerator and denominator are both positive, so the absolute value of the fraction is the fraction itself.

Example Use Cases

The absolute value of a fraction has many practical applications in mathematics and real-world problems. Here are a few examples:

Distance: The absolute value of a fraction can be used to represent distance. For example, if you are traveling at a speed of $\frac{11}{5}$ miles per hour, the absolute value of your speed is $\frac{11}{5}$ miles per hour.
Finance: In finance, the absolute value of a fraction can be used to represent the magnitude of a financial transaction. For example, if you have a stock that is worth $\frac{11}{5}$ dollars, the absolute value of the stock's value is $\frac{11}{5}$ dollars.
Science: In science, the absolute value of a fraction can be used to represent the magnitude of a physical quantity. For example, if you are measuring the speed of a particle that is traveling at $\frac{11}{5}$ meters per second, the absolute value of the particle's speed is $\frac{11}{5}$ meters per second.

Final Thoughts

In conclusion, finding the absolute value of a fraction is a simple process that involves calculating the absolute value of the numerator and denominator separately. The absolute value of a fraction has many practical applications in mathematics and real-world problems. By understanding how to find the absolute value of a fraction, you can apply this knowledge to a wide range of situations.
