Okay, ratios! Yah!
So heres how it works.
Lets just make sure we have the info.
So we have butter, sugar, and vanilla at a 23:8:1 ratio. We know that this all must add up to get 96 tablespoons.
Well look at that. There is a nice number we can use hidden in here.
Add up the ratio amounts and we have 32 tablespoons in total. Well thats easy. All we need to do is multiply by 3 and we get 96 tablespoons.
So, the answer would be 3 tablespoons of vanilla
