Question

using table radio 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 cups of  

the soup? 

Answer 1

For every proportion, the product of the extremes is always equal to the product of the means, i.e., a : b : : c : d if and only if ad = bc .

Here we have,

12:28::18:x

12x=28(18)

12x=504

x=504/12

x=42

42 ounces of beef broth is required to make 18 cups of soup.
