What is ratio of 2.5 cups all-purpose flour to cake flour?

To determine the ratio of 2.5 cups all-purpose flour to cake flour, you need to know the individual weights of each flour type and calculate their ratio based on weight. Here's how to do it:

1. Find the weight of 2.5 cups of all-purpose flour.

- 1 cup of all-purpose flour weighs approximately 120 grams (g).

- 2.5 cups of all-purpose flour = 2.5 x 120 g = 300 g.

2. Find the weight of an equal volume of cake flour.

- 1 cup of cake flour weighs approximately 110 grams (g).

- 2.5 cups of cake flour = 2.5 x 110 g = 275 g.

3. Calculate the ratio of all-purpose flour to cake flour by weight.

- Ratio = Weight of all-purpose flour / Weight of cake flour

- Ratio = 300 g / 275 g = 1.09:1

Therefore, the ratio of 2.5 cups all-purpose flour to cake flour is approximately 1.09:1.
