To revise the original recipe for Creamy Garlic Pasta, you have made adjustments to the ingredient amounts in three scenarios:

Scenario 1: Using 13th of the suggested amounts
To make a very small portion of the pasta, you can use only 1/13th of the suggested amounts for each ingredient. Here's the revised ingredient list:

- 9.23 grams (0.33 oz) of fettuccine pasta
- 1.54 grams (0.05 tbsp) of butter
- 0.31 cloves of garlic, minced
- 0.08 cups of heavy cream
- 0.02 cups (1.23 tsp) of grated Parmesan cheese
- Pinch of salt and black pepper

This will make approximately 0.15 servings.

Scenario 2: Tripling all ingredients
If you want to make a larger batch of the pasta, you can triple all the ingredients. Here's the revised ingredient list:

- 24 oz of fettuccine pasta
- 6 tbsp of butter
- 12 cloves of garlic, minced
- 3 cups of heavy cream
- 1.5 cups of grated Parmesan cheese
