A recipe calls for 2.3 cup of sugar for every 2 teaspoon of vanilla. How much sugar should be used for every 1 teaspoon of vanilla?

2.3 / 2 = 1.15 cup of sugar for each 1 tsp. of vanilla.

To determine how much sugar should be used for every 1 teaspoon of vanilla, we need to find the ratio between the amount of sugar and the amount of vanilla in the recipe.

According to the recipe, there are 2.3 cups of sugar for every 2 teaspoons of vanilla.

To find the amount of sugar for 1 teaspoon of vanilla, we can set up a proportion:

2.3 cups of sugar / 2 teaspoons of vanilla = x cups of sugar / 1 teaspoon of vanilla

Now, we can solve for x by cross-multiplying:

2.3 cups of sugar * 1 teaspoon of vanilla = 2 teaspoons of vanilla * x cups of sugar

2.3 cups of sugar = 2x cups of sugar

Finally, we can solve for x by dividing both sides of the equation by 2.3:

x = 2.3 cups of sugar / 2

x = 1.15 cups of sugar

Therefore, for every 1 teaspoon of vanilla, you should use 1.15 cups of sugar.
