1. What is Decimal to Fraction Conversion?

Decimal to fraction conversion is the process of expressing a decimal number as a fraction (a ratio of two integers). This is useful in many mathematical and real-world applications where fractions are preferred over decimal notation.

2. How Does the Conversion Work?

The conversion follows these steps:

Where:

• \( n \) — Number of decimal places
• \( 10^n \) — Multiplier to eliminate decimal

Explanation: The decimal is multiplied by 10 raised to the number of decimal places to convert it to an integer numerator, with 10^n as the denominator. This fraction is then simplified by dividing both numerator and denominator by their greatest common divisor (GCD).

3. Importance of Fraction Conversion

Details: Fractions are often preferred in certain contexts like measurements, ratios, and when exact values are needed (as some fractions can't be precisely represented in decimal form due to repeating decimals).

4. Using the Calculator

Tips: Enter the decimal number and specify how many decimal places to consider. The calculator will show the simplified fraction form. For repeating decimals, use the exact repeating pattern if possible.

5. Frequently Asked Questions (FAQ)

Q1: What if my decimal repeats infinitely?
A: For repeating decimals, use algebra to convert. For example, 0.333... = 1/3. Our calculator works best for terminating decimals.

Q2: Why does my fraction look complicated?
A: Some decimals convert to fractions with large numerators/denominators. The calculator simplifies them as much as possible.

Q3: How accurate is this conversion?
A: For the specified decimal places, it's mathematically exact. However, rounding may occur if you limit decimal places.

Q4: Can I convert negative decimals?
A: Yes, the calculator handles negative numbers by placing the negative sign on the numerator.

Q5: What's the maximum precision supported?
A: The calculator supports up to 6 decimal places for optimal performance and accuracy.
