Understanding Irrational Numbers

Irrational numbers are real numbers that cannot be expressed as a finite decimal or fraction. They have an infinite number of digits after the decimal point, and these digits never repeat in a predictable pattern. Examples of irrational numbers include the square root of 2, pi (π), and e. In this article, we will explore which number, when added to $\frac{3}{4}$, produces an irrational number.

The Number $\frac{3}{4}$

$\frac{3}{4}$ is a rational number, as it can be expressed as a finite fraction. It is a simple fraction with a numerator of 3 and a denominator of 4. When we add a number to $\frac{3}{4}$, we are essentially adding a fraction to another fraction.

Adding a Number to $\frac{3}{4}$

To determine which number, when added to $\frac{3}{4}$, produces an irrational number, we need to consider the properties of irrational numbers. An irrational number cannot be expressed as a finite decimal or fraction. Therefore, when we add a number to $\frac{3}{4}$, we need to find a number that, when added to $\frac{3}{4}$, results in a number that cannot be expressed as a finite decimal or fraction.

Analyzing the Options

Let's analyze the options given:

A. $\pi$ - Pi (π) is an irrational number. When we add $\pi$ to $\frac{3}{4}$, we get $\frac{3}{4} + \pi$. This is an irrational number because $\pi$ is an irrational number.

B. -0.75 - -0.75 is a rational number. When we add -0.75 to $\frac{3}{4}$, we get $\frac{3}{4} - 0.75$. This is a rational number because -0.75 is a rational number.

C. $\frac{3}{5}$ - $\frac{3}{5}$ is a rational number. When we add $\frac{3}{5}$ to $\frac{3}{4}$, we get $\frac{3}{4} + \frac{3}{5}$. This is a rational number because both $\frac{3}{4}$ and $\frac{3}{5}$ are rational numbers.

D. 0.333 - 0.333 is a rational number. When we add 0.333 to $\frac{3}{4}$, we get $\frac{3}{4} + 0.333$. This is a rational number because 0.333 is a rational number.

Conclusion

Based on our analysis, the only option that produces an irrational number when added to $\frac{3}{4}$ is option A, $\pi$. When we add $\pi$ to $\frac{3}{4}$, we get $\frac{3}{4} + \pi$, which is an irrational number.

Why is $\pi$ an Irrational Number?
