Chef Rita is cooking for a Sunday brunch. she knows that 22 pancakes can feed 8 people. She is wondering how many people she can feed with 55 pancakes. She assumes each person eats the same quantity of pancakes

Answers

Answer:

20 people

Step-by-step explanation:

22 pancakes = 8 people

55 pancakes = x people

=> Cross-multiply

=> 22 * x = 55 * 8

=> 22x = 440

=> 22x/22 = 440/22

=> x = 20

So, 55 pancakes can feed 20 people.
