How much chicken broth and rice dan needs to use for 9 people

Dan will need to use 4.5 cups of chicken broth and 3 cups of rice.

We need to find the unit amount (amount for 1 person first)

So I divided: 30/15=2 (chicken broth)

30/10=3 (rice)

Now we will need to see how many cups we would need of everything for 9 people:

So we need to divide what we got in the step above:

9/2=4.5 cups of chicken broth

9/3= 3 cups of rice

I hope you are having a great day, buddy :)
