> The mixed number to improper fraction calculator converts W n/d into a single fraction (W·d + n)/d and simplifies it.

## Inputs

- Whole number (W₁)
- Numerator (n₁)
- Denominator (d₁)

## Results

- Improper fraction
- Simplified
- Decimal
- Steps

## Formula

```
W n/d = (W × d + n) / d
```

## Explanation

Improper fractions are easier to multiply, divide and use in algebra than mixed numbers. The conversion is quick: multiply the whole number by the denominator and add the numerator.

### How to use the Mixed Number to Improper Fraction Calculator

- **Whole number (W₁)**
- **Numerator (n₁)**
- **Denominator (d₁)**

Everything is calculated in your browser, so results appear instantly and nothing you type is sent to a server.

### How it works

The whole number is multiplied by the denominator and added to the numerator; the denominator stays the same. The result is simplified if possible.

## Worked example

Inputs — Whole number (W₁): 2; Numerator (n₁): 3; Denominator (d₁): 4.

Results — **Improper fraction = 11/4**; Simplified = 11/4; Decimal = 2.75; Steps = 1. Multiply the whole number by the denominator: 2 × 4 = 8
2. Add the numerator: 8 + 3 = 11
3. Keep the denominator: 11/4.

## Key terms

- **Improper fraction**: A fraction whose numerator is at least its denominator.
