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

\frac{28}{12} \frac{ounces}{cups} =\frac{x}{18} \frac{ounces}{cups} \\ \\12*x=18*28\\ \\x=18*28/12\\ \\x=42\ ounces

therefore

the answer is

42\ ounces
