How much active dry yeast?

My jar of Fleischmann's active dry yeast says 2 1/4 teaspoons to each cake fresh yeast, which is 0.6 oz. That equals 7 1/2 teaspoons, or 2 1/2 tablespoons of active dry yeast. All this goes on the assumption that the recipe is asking for fresh yeast. Are these calculations correct? Thank you.
