Can somebody help me scale down this recipe? I can do all but the 1/3 cup of vegtable oil. ( I'm so bad with numbers,

) I need it halved. Here is the recipe. Black pepper bisquits.
1 tablespoon = 3 teaspoons
1 cup = 16 tablespoon = 8 ounces
1/4 cup = 4 tablespoons
1/3 cup = 5 tablespoons plus 1 teaspoon 1/6 cup = 2 1/2 TB (6 tsp + 1 1/2 tsp) + 1/2 tsp = 2TB + 2tsp
