Zahara mixed 5 quarts of dry ingredients and 2 quarts of water and a batch of concrete .She ran out of the mixture before finishing her project so she made another batch 10 quarts of dry ingredients . How many quarts of water does zahara need to add to keep the consistency the same? Complete the ratio square

4 quarts.

Step-by-step explanation:

Given data:

Amount of dry ingredients = 5 quarts.

Amount of water in the mixture = 2 quarts.

Solution:

Let’s a represent the amount of dry ingredients.

Let b represent the amount of water

For first Batch

a/b = 5/2.

b = 2/5a equation 1

For second Batch

a= 10

substitute a into equation 1 to solve for b

b = 2/5(10)

b = 4.

The ratio for batch b = 10/4.

Zahara needs to add 4 quarts of water to the mixture.
