Final answer:
To determine the amount of water needed for 5 cups of flour, set up a proportion and solve for the unknown variable. Therefore, you will need approximately 6.67 cups of water for 5 cups of flour.
Step-by-step explanation:
To find out how many cups of water you will need for 5 cups of flour, you can use a proportion. Since you know that 3 cups of flour require 4 cups of water, you can set up the proportion as follows:
3 cups of flour / 4 cups of water = 5 cups of flour / x cups of water
Cross multiplying and solving for x, you get:
3x = 20
x ≈ 6.67
Therefore, you will need approximately 6.67 cups of water for 5 cups of flour.
