To make a soup, 2 cups of chicken broth are needed for each 1/4 cup of dried lentils. How many cups of chicken broth are needed if 2 1/4 cups of dried lentils are used?

You'll need 18 cups of chicken broth!

Step-by-step explanation:

You are using a ratio of 1/4 cup (lentils) to 2 cup (broth). Therefore, you need to find the relationship between lentil and broth.

In order to get from 1/4 to 2, you multiply by 8. (1/4 * 8 = 2) Therefore, the common relationship is multiplying the lentil amount by 8 So, 2 1/4 * 8 = 18

Therefore, 18 cups are needed : D
