Oscar is making a loaf of bread in cooking class. The teacher gives him a recipe that calls for 3/4

tsp of yeast for every 1/2
cup of flour. If he plans to use 1 tsp of yeast, how much flour does he need in order to keep the bread tasting the same?(1 point)

To determine how much flour is needed when using 1 tsp of yeast, we can set up a proportion based on the recipe.

The original ratio from the recipe is:

  • 3/4 tsp of yeast for every 1/2 cup of flour.

We can express this in terms of amounts of yeast per each corresponding amount of flour. Let's set up the proportion:

  1. The ratio of yeast to flour in the original recipe is: \[ \frac{3/4 \text{ tsp}}{1/2 \text{ cup}} \]

  2. If Oscar uses 1 tsp of yeast, we can set up the ratio as: \[ \frac{3/4 \text{ tsp}}{1/2 \text{ cup}} = \frac{1 \text{ tsp}}{x \text{ cup}} \] where \( x \) is the amount of flour needed.

  3. We can cross-multiply to find \( x \): \[ 3/4 \cdot x = 1 \cdot 1/2 \] \[ 3x = 2 \] \[ x = \frac{2}{3} \text{ cup} \]

Thus, Oscar needs 2/3 cup of flour in order to keep the bread tasting the same when using 1 tsp of yeast.

So, the correct response is: Start Fraction 2 over 3 End Fraction cup
