If the recipe calls for 3 tablespoons of kernels and Jennie uses 10 tablespoons, then she is using 10/3 times the amount of kernels specified in the recipe.

If the recipe calls for 1/2 cup of butter, Jennie needs to multiply the amount by 10/3 to find how much butter she needs.
1/2 cup * 10/3 = 5/3 cups of butter
Rounded to the nearest hundredth, Jennie needs 1.67 cups of butter.
