Introduction

In mathematics, expressions are a fundamental concept that helps us represent and solve problems. An expression is a combination of numbers, variables, and mathematical operations that can be evaluated to produce a value. In this article, we will evaluate the expression $-\frac{1}{1}$ , which is a simple yet important example of how to handle negative fractions.

Understanding Negative Fractions

A negative fraction is a fraction that has a negative sign in front of it. In the expression $-\frac{1}{1}$ , the negative sign is in front of the fraction $\frac{1}{1}$ . To evaluate this expression, we need to understand the concept of negative fractions and how to handle them.

What is a Negative Fraction?

A negative fraction is a fraction that has a negative sign in front of it. For example, $-\frac{1}{2}$ is a negative fraction because it has a negative sign in front of the fraction $\frac{1}{2}$ . Negative fractions are used to represent a value that is less than zero.

Evaluating the Expression

To evaluate the expression $-\frac{1}{1}$ , we need to follow the order of operations (PEMDAS):

Evaluate the fraction $\frac{1}{1}$ .
Apply the negative sign to the result.

Evaluating the Fraction

The fraction $\frac{1}{1}$ is equal to 1, because any number divided by itself is equal to 1.

Applying the Negative Sign

Now that we have evaluated the fraction, we can apply the negative sign to the result. The negative sign in front of the fraction $\frac{1}{1}$ means that we need to multiply the result by -1.

Multiplying by -1

Multiplying a number by -1 is equivalent to changing the sign of the number. For example, multiplying 1 by -1 gives us -1.

Conclusion

In conclusion, the expression $-\frac{1}{1}$ is equal to -1. This is because the negative sign in front of the fraction $\frac{1}{1}$ means that we need to multiply the result by -1, which gives us -1.

Examples and Applications

The expression $-\frac{1}{1}$ is a simple example of how to handle negative fractions. However, there are many other examples and applications of negative fractions in mathematics and real-life situations.

Examples of Negative Fractions

$-\frac{1}{2}$ is a negative fraction that is equal to -0.5.
$-\frac{3}{4}$ is a negative fraction that is equal to -0.75.
$-\frac{2}{3}$ is a negative fraction that is equal to -0.67.

Applications of Negative Fractions

In finance, negative fractions are used to represent a loss or a decrease in value.
In science, negative fractions are used to represent a decrease in a physical quantity, such as temperature or pressure.
In engineering, negative fractions are used to represent a decrease in a system's performance or efficiency.

Final Thoughts

In conclusion, the expression $-\frac{1}{1}$ is a simple yet important example of how to handle negative fractions. By following the order of operations and applying the negative sign, we can evaluate the expression and understand the concept of negative fractions.
