## About
The Recipe Scaler multiplies the quantities in a recipe to suit the number of people you are cooking for. Paste one ingredient per line, enter how many servings the recipe makes and how many you want, and it scales each leading number, including fractions such as 1 1/2 or ½. Lines without a number, like “salt to taste”, are left alone. Results are shown as neat fractions where they are close to one.

## How to use
1. Paste the ingredients, one per line.
2. Enter how many servings the recipe makes and how many you need.
3. Read the scaled list and copy it. Fractions are shown as, for example, 1 1/2.
