There are 2.5 tsp vanilla needed for 5 cups of flour. I solved this by putting the given info into a ratio- cups of flour/tsp. vanilla. Then, i put in the given information and cross multiplied to solve for x. I hope this helped you!! :))

2 1/2 teaspoons of vanilla. Because 5/3=1.67, then 1 1/2x1.67= 2 1/2.
