## Overview

The Fraction Calculator instantly evaluates complex fraction expressions, providing results in simplified fraction, mixed-number, and decimal formats. Whether you are adding, subtracting, multiplying, or dividing rational numbers, this tool handles parentheses and mixed operations while allowing you to customize the decimal precision of the final output.

## Inputs

- **Fraction Expression** (text): 3/4 + 5/6 * (2 - 1/3)
- **Decimal Precision** (number)

## When to use

- Verifying math homework and classroom calculations involving complex rational numbers.
- Converting and scaling fractional measurements for cooking, carpentry, or DIY projects.
- Simplifying multi-step fraction expressions for engineering and technical documentation.

## How it works

- Enter your mathematical expression using fractions, integers, operators (+, -, *, /), and parentheses.
- Adjust the decimal precision setting to determine how many decimal places to display in the final output.
- The calculator evaluates the expression following the standard order of operations.
- View the exact result simultaneously as a simplified fraction, a mixed number, and a rounded decimal.

## Use cases

- Students and teachers checking step-by-step arithmetic on multi-term fraction equations.
- Woodworkers and builders calculating precise material cuts by adding or subtracting fractional inch measurements.
- Chefs and bakers scaling recipes up or down by multiplying ingredient fractions.

## Frequently asked questions

### Can I use parentheses in my fraction expressions?

Yes, the calculator fully supports parentheses to group operations and enforce a specific calculation order.

### Does the tool simplify the final fraction automatically?

Yes, all results are automatically reduced to their simplest fractional form.

### How do I input a mixed number?

You can input mixed numbers by adding an integer and a fraction inside parentheses, such as (2 + 1/2).

### What is the maximum decimal precision I can set?

You can configure the decimal precision up to 10 decimal places using the precision setting.

### Can I mix whole numbers and fractions in the same equation?

Absolutely. The calculator seamlessly handles expressions containing integers, proper fractions, and improper fractions together.
