A recipe requires 3/4 cup sugar. If you triple the recipe, how many cups of sugar are needed?

• A. 2
• B. 2.25
• C. 3
• D. 1.5

Answer: (B)

Scaling a recipe means multiplying each ingredient by the same factor. Here, tripling means multiplying the sugar by 3. Compute (3/4) × 3 = (3×3)/4 = 9/4, which equals 2.25 cups (or 2 and 1/4 cups). So you’d need 2.25 cups of sugar.
