Complete question is;
Four students plan to share the cost for ordering pizza. Each student says how much of a whole pizza they want to eat as shown. Abe = 1/2 of a pizza, Becca = 2/3 of a pizza, Cam = 2/4 of a pizza and Kim 2/6 of a pizza. Abe and Becca only want pepperoni pizza. Cam and Kim only want cheese pizza. Cheese and pepperoni pizzas can only be ordered as whole pizzas. What is the minimum number of whole pizzas they must order so that each student has as much of the kind of pizza they say they want to eat?
Answer:
3 whole pizzas
Explanation:
We are told that the fraction of pizza they each want are;
Abe = ½ of a pizza
Becca = ⅔ of a pizza
Cam = 2/4 of a pizza
Kim = 2/6 of a pizza.
Now, Abe and Becca only want pepperoni pizza.
Thus,
For total pepperoni pizza for Abe and Becca = ½ + ⅔ = 7/6 = 1.167
Since it's only a full pizza that can be ordered, then they must order 2 pepperoni pizzas
Also, Cam and Kim only want cheese pizza.
Thus;
Total cheese pizza to be ordered = 2/4 + 2/6 = 5/6 = 0.833
Since it's only a full pizza that can be ordered, then they must order at least 1 cheese pizza.
Thus, minimum number of whole pizzas they must order = 2 + 1 = 3 whole pizzas
