Answer 2

The amount of ingredients necessary to serve 5 people are :

$3\dfrac{3}{4}$ cups spaghetti sauce

$2\dfrac{1}{2}$ cups ricotta cheese

$2\dfrac{1}{2}$ cups mozzarella.

Explanation:

Given : The number of cups of spaghetti sauce required for 8 servings =6

⇒ The number of cups of spaghetti sauce required for 1 serving = $\dfrac{6}{8}=\dfrac{3}{4}$

⇒ The number of cups of spaghetti sauce required for 5 serving = $\dfrac{3}{4}\times5=\dfrac{15}{4}=3\dfrac{3}{4}$

The number of cups of ricotta cheese required for 8 servings =4

⇒ The number of cups of ricotta cheese required for 1 serving = $\dfrac{4}{8}=\dfrac{1}{2}$

⇒ The number of cups of ricotta cheese required for 5 servings = $\dfrac{1}{2}\times5=2\dfrac{1}{2}$

Similarly , The number of cups of mozzarella cheese required for 8 servings =4

The number of cups of mozzarella cheese required for 5 servings = $2\dfrac{1}{2}$

Hence, the amount of ingredients necessary to serve 5 people are :

$3\dfrac{3}{4}$ cups spaghetti sauce

$2\dfrac{1}{2}$ cups ricotta cheese

$2\dfrac{1}{2}$ cups mozzarella.
