Final answer:

Omilia needs 9.5 more cups of water.

Step-by-step explanation:

To find out how many more cups of water Omilia needs, we first need to determine the total amount of flour-water mixture she is making. Since the ratio of flour to water is 1:3, for every 1 cup of flour, she needs 3 cups of water. She starts with 4 cups of flour, so she should mix 4 x 3 = 12 cups of water in total.

Next, we subtract the amount of water she has already mixed (2.5 cups) from the total amount she needs (12 cups):

12 cups - 2.5 cups = 9.5 cups

Therefore, Omilia needs 9.5 more cups of water.

Answer: Below

Step-by-step explanation:

We know that water must be three times flour, so our end goal is 12 cups of water, since 4 * 3 = 12.

We already have 2.5 and 4, so we make the equation:

2.5 + x = 12

Simplify.

x = 7.5

Our answer is 7.5
