Question

At a restaurant, a serving of chicken noodle soup is 3/4 cup. A serving of vegetable soup is 2/3 cup. The restaurant sold 20 servings of chicken noodle soup and 18 servings of vegetable soup. How many more cups of chicken noodle soup did they sell than cups of vegetable soup?

Answer 1

Answer:

$3\ cups$

Step-by-step explanation:

Part A)

we know that

A serving of chicken noodle soup is $3/4$ cup

so by proportion

Find how many cups are $20$ servings of chicken noodle soup

$\frac{(3/4)}{1}\frac{cup}{serving} =\frac{x}{20}\frac{cup}{serving}\\ \\x=20*(3/4)\\ \\x=15\ cups$

Part B)

we know that

A serving of vegetable soup is $2/3$ cup

so by proportion

Find how many cups are $18$ servings of vegetable soup

$\frac{(2/3)}{1}\frac{cup}{serving} =\frac{x}{18}\frac{cup}{serving}\\ \\x=18*(2/3)\\ \\x=12\ cups$

Part C)

Find the difference

$15\ cups-12\ cups=3\ cups$

Answer 2

18 x 2/3 = 12 cups
3/4 x 20 = 15 cups
3 more cups
