What quantity of vanilla would you need to make a half recipe? Very cherry pie INGREDIENTS: \( 4 \frac{1}{2} \) cups cherries 2 cups sugar \( \frac{1}{4} \) cup flour \( 2 \frac{1}{2} \) teaspoons vanilla 1 teaspoon cinnamon 1 pie crust Write your answer as a fraction or as a whole or mixed number. \( \square \) teaspoons

1. The full recipe requires \(2 \frac{1}{2}\) teaspoons of vanilla, and this can be written as an improper fraction: \[ 2 \frac{1}{2} = \frac{5}{2} \text{ teaspoons.} \] 2. To make a half recipe, multiply the vanilla amount by \(\frac{1}{2}\): \[ \frac{1}{2} \times \frac{5}{2} = \frac{5}{4}. \] 3. Express \(\frac{5}{4}\) as a mixed number: \[ \frac{5}{4} = 1 \frac{1}{4} \text{ teaspoons.} \] Thus, you need \( \boxed{1 \frac{1}{4}} \) teaspoons of vanilla.
