Question

josh mixed 5 quarts of dry ingredients and 2 quarts of water to make a batch of concrete. he ran out of the mixture before finishing her project so she made another batch using 10 quarts of dry ingredients

Answer 1

how many quarts of water does josh need to add to keep the consistency the same? complete the ratio square.
batch 1 has 5 on the top and 2 on the bottom 5 is the dry ingredients and 2 is the water. batch 2 has 10 dry ingredients and a empty box under it

Answer 2

and 4 quarts of water. How many total quarts of dry ingredients did Josh use for his project?

5 quarts + 10 quarts = 15 quarts

Josh used a total of 15 quarts of dry ingredients for his project.

Answer 3

To keep the consistency the same, the ratio of dry ingredients to water should remain constant.

Batch 1: 5 quarts of dry ingredients to 2 quarts of water = 5:2
Batch 2: 10 quarts of dry ingredients to x quarts of water = 10: x


To find the value of x, we can set up a proportion:

5/2 = 10/x

Cross multiply:
5x = 20
x = 20 / 5
x = 4

So, Josh needs to add 4 quarts of water to keep the consistency the same.
