## What this calculates

Convert any decimal number to its simplest fraction form with this free calculator. Enter a decimal and instantly see the equivalent fraction, mixed number, numerator, and denominator.

## Inputs

- **Decimal Number** — The decimal number to convert to a fraction.

## Outputs

- **Simplified Fraction** — formatted as text — The decimal expressed as a simplified fraction.
- **Mixed Number** — formatted as text — The fraction expressed as a mixed number (if improper).
- **Numerator** — The top number of the fraction.
- **Denominator** — The bottom number of the fraction.

## Details

Converting decimals to fractions is a common task in math, cooking, engineering, and many other fields. Every terminating decimal can be expressed as a fraction by placing the decimal digits over a power of 10, then simplifying.

How to Convert a Decimal to a Fraction

- Count the number of decimal places.

- Write the decimal as a fraction with the appropriate power of 10 as the denominator.

- Simplify by dividing both numerator and denominator by their greatest common divisor.

For example, 0.375 has 3 decimal places, so it becomes 375/1000. The GCD of 375 and 1000 is 125, so the simplified fraction is 3/8.

Mixed Numbers

When the decimal is greater than 1 (or less than -1), the result can be written as a mixed number combining a whole number and a proper fraction. For instance, 2.75 = 2 and 3/4.

## Frequently Asked Questions

**Q: How do I convert a decimal to a fraction?**

A: Write the decimal digits as the numerator over a power of 10 matching the number of decimal places. Then simplify by dividing both parts by their greatest common divisor. For example, 0.6 = 6/10 = 3/5 after dividing by 2.

**Q: What about repeating decimals like 0.333...?**

A: Repeating decimals can be converted to fractions using algebra. For 0.333..., let x = 0.333..., then 10x = 3.333..., so 9x = 3, giving x = 1/3. This calculator handles terminating decimals; for repeating decimals, enter a rounded approximation for a close fractional equivalent.

**Q: What is a mixed number?**

A: A mixed number combines a whole number with a proper fraction. It is used when the fraction is improper (numerator larger than denominator). For example, 7/4 as a mixed number is 1 and 3/4. Mixed numbers are often more intuitive for everyday use.

**Q: Why do we simplify fractions?**

A: Simplified (or reduced) fractions are easier to understand and compare. Two fractions like 4/8 and 1/2 represent the same value, but 1/2 is simpler. Simplifying divides both the numerator and denominator by their greatest common divisor to get the smallest equivalent fraction.

**Q: Can every decimal be written as a fraction?**

A: Every terminating decimal and every repeating decimal can be written as a fraction of two integers (a rational number). However, irrational numbers like pi (3.14159...) and the square root of 2 (1.41421...) have non-terminating, non-repeating decimals and cannot be exactly expressed as fractions.
