Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs. Suppose Karl onlyhas a dozen eggs. How many batches of cookies could he make?

Answers

Answer 1

Answer:

Answer:

$5\ batches\ of\ cookies$

Step-by-step explanation:

we know that

Karl makes 7 1/2 batches of cookies using 1 1/2 dozen eggs

so using proportion

Find out how many batches of cookies could he make with a dozen eggs

step 1

Convert mixed numbers to an improper fraction

$7(1)/(2)=(7*2+1)/(2)=(15)/(2)$

$1(1)/(2)=(1*2+1)/(2)=(3)/(2)$

step 2

Applying proportion

Let

x ----> the amount of batches of cookies

$((15/2))/((3/2))(batches)/(dozen\ eggs)=(x)/(1)(batches)/(dozen\ eggs)\n\nx=(15)/(3)\n\nx=5\ batches\ of\ cookies$

Maria is making a gelatin dessert for a party. She plans on making 12 servings for every 6 people. If each pan Maria uses to make the dessert holds 8 servings, what is the minimum number of these pans will she needs in order to serve 112 people?Please I really need help.

Answers

Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!
