1 answer

The ratio of yeast to flour is 3/4 f tsp of yeast for every 1/2 cup of flour. To find the amount of flour needed for 1 tsp of yeast, we can set up a proportion:

(3/4 f tsp yeast) / (1/2 cup flour) = (1 tsp yeast) / (x cup flour)

Cross multiplying, we get:

(3/4 f tsp yeast) * (x cup flour) = (1 tsp yeast) * (1/2 cup flour)

Simplifying, we have:

(3/4 f * x) tsp yeast * cup flour = 1/2 tsp yeast * cup flour

Canceling out the units, we have:

(3/4 f * x) = 1/2

Solving for x, we get:

x = 1/2 * (4/3 f)
= 2/3 f

So, Oscar needs 2/3 cup of flour to keep the bread tasting the same.

Therefore, the answer is C. 2/3 cup.
