Final answer:
To convert active dry yeast to instant yeast, multiply the quantity of active dry yeast by a conversion factor of 0.75.
Step-by-step explanation:
To convert active dry yeast to instant yeast, you need to multiply the quantity of active dry yeast by a conversion factor of 0.75. This means that if a recipe calls for 1 teaspoon of instant yeast, you would need to use 1 1/4 teaspoons of active dry yeast. The conversion factor accounts for the differences in their composition and activity levels.
