Question

Marcus is making homemade barbecue sauce. The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard. What is the rate in cups of ketchup per cup of mustard?

Answer 1

Answer: 6 cups of ketchup per cup of mustard

Step-by-step explanation:

Given : The recipe calls for 3 cups of ketchup for every $\dfrac12$ cup of mustard.

That means , for $\dfrac12$ cup of mustard. we need 3 cups of ketchup.

By using proportions, if we multiply 2 on both sides ,we get

for  $\dfrac12\times 2$ cup of mustard. we need $3\times 2$ cups of ketchup.

⇒ for  $1$ cup of mustard. we need $6$ cups of ketchup.

Hence, the required rate = 6 cups of ketchup per cup of mustard
