You just opened the trendiest food truck in town. Five-star reviews mean scaling your signature recipe perfectly — keep the ratio exact, no matter how many customers line up.
A ratio compares two quantities. When you scale a recipe, the amounts grow but the ratio stays the same — that's what keeps every batch tasting identical. These are equivalent ratios.
Your batter is 3 cups flour : 2 cups sugar for every 4 servings. Drag the slider — watch the bowl and the table scale, and notice the ratio never changes.
| Servings | Flour (cups) | Sugar (cups) | Ratio |
|---|
