Answer: Use % of the original ingredient amounts.

Type of calculation: Calculating what percentage one number is of another.
How to use the calculator: Use the Part-to-Whole Percentage CALCULATOR ("What percentage of Y is Z?"). Enter the original servings as 6 [Y] and the new servings as 2 [Z]. It will show you what percentage 2 is of 6.
The formula:
We want to know what percentage 2 is of 6.
Formula: (Part / Whole) × 100%
Percentage = (2 / 6) × 100% = 0.3333333333333333 × 100% = 33.33%
