Step 1 — Portion ControlPaso 1 — Control de Porciones

Divide a recipe amount by a portion serving sizeDivide la cantidad de una receta por el tamaño de porción de servicio
Your job: Enter or select the total amount of an ingredient you have (dividend) and divide it by the portion size (divisor). Find the quotient to see how many portions you can serve. Tu trabajo: Ingresa o selecciona la cantidad total de un ingrediente que tienes (dividendo) y divídela por el tamaño de la porción (divisor). Encuentra el cociente para ver cuántas porciones puedes servir.

To divide fractions, multiply the first fraction (dividend) by the reciprocal of the second fraction (divisor).
Formula: A/B ÷ C/D = A/B × D/C = (A × D) / (B × C). Para dividir fracciones, multiplica la primera fracción (dividendo) por el recíproco de la segunda fracción (divisor).
Fórmula: A/B ÷ C/D = A/B × D/C = (A × D) / (B × C).

Step 2 — Big Batch Servings

Divide a whole number batch by a unit fraction scoop
Your job: You made a large batch of batter (measured in whole cups). How many servings can you get if you measure them out using a unit fraction scoop?

🍞 King Arthur Baking — Recipes ↗King Arthur Baking — Recetas ↗ Find: A recipe with fraction measurements to scaleBuscar: Una receta con medidas en fracciones para escalar
🟢 Level 1 support: Choose a whole number batch (e.g. 4 cups flour) and a unit fraction scoop (e.g. 1/3 cup). The visualizer will draw 4 cups and divide each cup into 3 portions, showing exactly 12 servings.
LEVEL 2 CHALLENGE
Input any whole number (dividend) and any unit fraction denominator (divisor). For example, a 7-cup batch divided by 1/5-cup scoops.
Need a hint?

Dividing a whole number by a unit fraction (1/d) is simple: multiply the whole number by the denominator (d).
Why it works: Each 1 whole contains exactly 'd' groups of 1/d. So 'W' wholes contain W × d groups.

Step 3 — Roll Cuts

Divide a mixed number roll length by a fraction slice size
Your job: You have a long cylinder of rolled dough (mixed number length) and want to slice it into equal pieces. Find the quotient to see how many slices you get, and compare your output to real-world bakery yields.
🟢 Level 1 support: Use a roll of length 2 1/2 feet and cut slices of 1/4 foot. The baguette visualizer will show exactly 10 slices can be cut.
LEVEL 2 CHALLENGE
Specify custom mixed numbers for the roll length and custom proper fractions for the slice size. The calculator will automatically convert the mixed number to an improper fraction first.

🥯 Real-World Bakery Yields

Compare your roll cut slice yield against typical professional bakery batch ranges:

Bakery Item Slice / Portion Yield Range Dough Prep Method
Croissants 6 – 8 per batch Laminated butter layers
Cinnamon Rolls 8 – 10 slices per log Spiral yeast roll-up
Artisan Baguette 12 – 16 slices per loaf Classic french roll cuts
Sourdough Loaf 10 – 14 slices per loaf Rustic scoring & slicing
Need a hint?

1. Convert the mixed number length (W N/D) to an improper fraction: (W × D + N) / D.
2. Divide the improper fraction by the slice size (multiply by reciprocal).
Example: 2 1/2 = 5/2. Then 5/2 ÷ 1/4 = 5/2 × 4/1 = 20/2 = 10 slices.

Step 4 — Compare With a Partner

Swap recipe results with a classmate and compare yields
Your job: Interview a classmate about their bakery numbers. Enter their name and their calculated servings below to compare your bakery yields.
