A recipe for one batch of cookies uses 5 cups of flour and 2 teaspoons of vanilla. If you use 20 cups of flour how many cups of vanilla should i use

0.1666 cups vanilla or 8 teaspoons

Step-by-step explanation:

5 cups flour = 2 tsp vanilla

multiply each side by 4

20 cups flour = 8 tsp vanilla

there are 48 tsp in a cup, so divide 8 by 48

20 cups flour = 0.1666 (repeating decimal) cups vanilla
