Question

A recipe that yields 12 cups of soup calls for 28 ounces of beef broth.how many ounces of beef broth do you need to make 18 of the soup?

Answer 1

we know that

A recipe that yields
`12` cups of soup calls for
`28` ounces of beef broth

so

by proportion

Find the ounces of beef broth needed to make
`18` cups of soup

`(28)/(12) (ounces)/(cups) =(x)/(18) (ounces)/(cups) \\ \\12*x=18*28\\ \\x=18*28/12\\ \\x=42\ ounces`

therefore

the answer is

`42\ ounces`
